Quite frustrating... it's hard to see where the barriers will be until you've already crashed! Nice visual/audio theme, though

Like a better version of Flappy-Whatever. I couldn't get higher than 2, but I really liked doing a loop-the-loop underwater to aim better or doing a backflip :)

This game is awesome... Like flappy bird but better!
The music is great, and the whole thing is beautifully simple yet fun.
If it were a free app, I'd download it.

This is really hard!! Best I could do was 3. I like the concept though :) Very fun and adds a twist to something familiar.

I really like the game. It's kinda like flappy birds - takes time to learn but once you do, you're hooked.

I loved the music changing on each play. Determining if the hole is over water makes me antsy but I see that as a good quality. Great job :)

I loved the controls and the concept was great, but the game was extremely challenging.

Very difficult. But fun.

Addicting. I got 7, but man did i feel like free willy!
Thanks for this.

Annoying and addicting at the same time. Surprising how something that is this unfair can be this fun.

I liked the game a lot. Pretty frustrating and addictive :) Great job in just 4 hours!

It's really a skill-based action game, I like it!

I could only get two. I suck.

Damn that's difficult! Good job for such a quick project!

Super hard. Exactly how I like it!

Really addictive and frustrating at the same time. Really nice entry for something made in 4 hours. Good job!

I really enjoyed controlling the sub - give me enemies to bomb and this would be awesome!

haha awesome. Loved the atmosphere with the cool music and jet stream. sexy.

This game just feels really good, I'd love to see it fleshed out.

Okay. I had fun, a bit irritated at the impossibility of some of the pillars, but this is somewhat adorable and I still had fun. Nicely done.

Very flappy-bird-esque but fun.

A bit challenging since you can't see where the opening is for the barriers till you're about to run into it. I like being able to back up/reverse direction to correct though.

Really smooth and nice, and I enjoyed the audio changing every play so it wouldn't get old. :)

This is the sort of single-concept game that jams are good for, but the execution is lacking. There's not enough responsiveness in the controls, and seeing where the openings are feels awkward.

I really enjoyed this, besides the frustration XD New flappy!

It's not an "easy to pick up, hard to master" kind of game. Hard as nails right from the start, but not frustrating at all! I really wanted to get better even when I was failing epicly. Great job!

For 4 hours, this is pretty nice. Better than some I've seen made in the full timeframe ;) it's still a bit too minimalistic though, but I think you're aware of that.

super clever idea. good twist on flappy that uses the theme well to differentiate. feels amazing when you jump out of the water and clear a high gap.

it's too hard to get into a flow though, since you've got to constantly make one pass and loop around again once you see the opening. if you just added an indicator on the right side of the screen it would make this soo good (imo)

Not my cup of tea but I enjoyed it, runs pretty smooth and the sound played gives it a good rhytim.
It feels quite polished as well, for the short amount of time invested, I can picture people getting addicted to it...
Just do the port to iOS/Android and get rich & famous!

I got to 9. I can die a happy man.

12. Can you please upload a windows build?

FUN! i enjoyed this way more than i should have : d took me quite some time to understand why the sub would stop to accelerate but after that i managed to score 8 (- ; nice music and simplistic but great art.

good work! Looking forward to your next game

Hard, but I think it's supposed to be that. I think it's a good concept and has a good execution. The controls were good and it's a fun game. Good work.

Awesome game! I got a score of 4, do I get a cookie?

Very frustrating we can't control the reactor. But it's pretty good for 8 hours!
Not sure how to feel and rate all those flappy bird clones though :/

One of the best games I've played so far in the competition, extremely fun and addicting, with amazing graphics, music, and controls!

In short, a fantastic effort for such a short length of time. I had a similarly-constrained time frame to do my entry, yet nowhere did I get as far as you.

Addictive

Love the twist. It feels so good to make the high jumps. Best I got was 7, but I have a sneaking suspicion that I'll be coming back to have one more go... then another... and another... :)

I've managed to get to 8 points with great effort, it feels so satisfying to make a perfect jump, I like that :)

This game was very frustrating; the submarine engine seems to work at random, and the barrier were quite hard to dodge. Then again, I generally am bad at this kind of infinite avoid-obstacles games...
The music was nice though, I liked the variations. It kept me a little bit longer on the game ^^'

Very addictive! ^^
Audio was fantastic and the graphics totally worked! Good job!

Score of 2. Definitely very good for 2 hours. I first thought ti was going to be a flappy bird clone.

I could only get a 5, those high gaps would always kill me! The game is really a lot of fun and it felt great to launch myself out of the water. Considering it was made in only 4 hours this is terrific!

This game is very difficult but also very fun. Checked this out because I saw a neat-looking gif in the post mortems

Sadly, you do not get Front Flip For Style points, nor do you get points for backflipping through a gate you've already crossed and that makes me very sad

You did some really cool stuff with the music, too. Congrats on a solid entry!

I'm not a fan of music that restarts whenever I respawn since I only hear the opening of every song, and it becomes more repetitive.

4 was my best.

solid game - really enjoyable with a lot of potential - awesome job

What do i think of this game? I FUCKING LOVE IT! Got 7 after a few tries. Absolutely love the gravity/physics switch from above and below water. Great job. Fun and addictive.

Great concept. Really brutal. Hard to see where the next gate would be sometimes and those air gates are brutal. Overall, good work!

I love this game, it's so peacefully frustrating and I spent 5 hours trying to find this game, just so I could rate it after I cleared my computer. 5/5 please make it easier

Fun little game. Took me a while to figure out I was actually coming out of the water, I thought the background was just some sort of gradient. I could just be dumb though. I like the way the music changes instruments, that was neat. Presentation is simple but pleasing. Nice work!

Great Entry! One of the most fun games in this LD! I will definitely replay it!

Thanks for all the replies!

New highscore: 58

wow, so simple and so cool, i love it! the feel of it is great, but hard at the very start. once i got it i really enjoyed it

That was amazing.

5 stars for fun.

I only got to 6. It's really awesome being made in only 4 hours. :O

A very hard and "flappy" game, but the movement felt really good. Visuals and audio are also nice, good job overall!

As much as I would like to consider myself awesome, I only managed to score 5 (after several attemps)

Smooth and fun to play. Tricky to master! great work.

Quite fun, but controls are too inertia-heavy for me. Would be cool if you cool glide while in air and affect and change your flight.

Hard but very smooth mechanic. I think it's nice entry with styles aesthetics.

After playing for ages I have highscore of 22.

Wow! Very addicting. Great job!

Cool game for such a short time! Controls were something new and difficult to explore. I learned to be very careful, and I tried many times but I never did better than four. Well done!

I tried it because I saw your blog post with the animated gif, and I also made a game about a ship that moves in curves under water, but it turns out they are very different.

Cool game!!!
