great game!

Great game !! It was tough but I made it through the levels !
The sound could be better, but the gameplay concept is really interesting. The graphics looks good.

Well done. There's a solid sense of style to the graphics, and the levels are challenging and engaging.

Love the dual gameplay concepts

Awesome game! Its hard, but do able and a cool puzzle/platformer mix. Made me think!

I like the concept. However, I find the game quite difficult due to the sliding effects.
I like the simple graphics style. Looks very clean.

Liked the gameplay and graphics.

Nice Try !

Awesome!

Cool concept. Love how you can trap yourself within a block :P

Nice idea and it works well. Would like some nice background music to go with it though :)

Great game!. Frustrating, but in a good way. Graphics are simple but effective.

I'd love you forever if you made this a full game! I had a ton of fun playing this!

This game was so simple to learn and so hard to master....I enjoyed it immensely.

Awesome! I couldn't beat the second level, but I'm really bad at these types of games, so it's not your fault.

Not bad :D

Very interesting gameplay.

Solid little concept. Nicely done.

Great game. I'm a fan of your work. Keep it up!

Good game! The graphics are nice too. You should make a version where the toggle happens every some time interval.

Amazing game, love the idea, also looks nice. Only sliding is a little annoying for me, hard to stay in place after jump.

That's a really great entry. Challenging and well crafted. you really have to kind of switch your brain to get past some levels. I also like the look.

Great idea! The platforming mechanic is too hard for me though. I couldn't manage to stay on the small blocks in the second level while at the same time thinking about the perspective... ;)
Oh and nice graphics!

Incredible game, super concept. On a couple of levels I thought: "Wow, genius level design". And I managed to finish it, feels so good :D Maybe the inertia of the ball could be lower cause it can get frustrating really fast...

Really fun game! Had me hooked for some time!

Very cool concept! I wasn't very good at it but I loved playing it anyway! ^^

Great game! I love the Game Boy-esque style! The levels are challenging but not too hard. The jump sound is cute :P

Awesome. I really liked the core mechanic and the level design was spot-on. The controls were a little slippery, and there was no background music. Really, those are the only drawbacks; it was a marvelous game.

This match really well with the theme. It is interesting and challenging. The draggin of the ball is too long doing the controls really hard to achieve simple things. The graphics are minimalistics and well done.

Great mechanic! I managed to get all the way to the end, though it took me awhile to map my brain to my fingers properly :) Well done!

This was a very good game. I'v seen similar ones before, but this was just really entertaining. I love the oldschool feel too! The level designs were all good, as was most of the other aspects. Well done, or should I say, well played ;)

You might want to post a runnable jar instead of a .rar file

One of my favourite entries so far!

I didn't get very far myself, but I watched Wertle play it much more easily than me - and I really love the concept and level design!

Three pointers how the game would've been more accessible for me:
- Being allowed to still jump if I pressed the shift buttons a few milliseconds before the jump key.
- No inertia.
- Using for example Space or X to jump - it's not really "up" in the opposite world. I can grasp the concept of jumping/falling in mirrored directions, but pressing up to go down is of a discrepancy.

So far a lot of people have been pointing out the slipperiness of the player. I feel like infinite acceleration would have made the game different in an awkward way. For that reason, I kept the sliding effect in. It's just part of the game mechanic. As is the first point you mentioned.

The third point is something I didn't think about. I probably should have included the down button, but I simply never saw it from that perspective.

This is really good, especially for your first time.
The gameplay is challenging, but not too challenging. I like it.

I liked it, made me think for a couple of them. The guy seems a little "slippery" but it added to the challenge in a fun way.

Good game, fantastic graphics :)

Really nice game! I found the controls a little difficult with the slide after you land, concept is awesome though

Such a cool mechanic! The simple graphics are nicely misleading - the depth of this game ramps up a lot and I'm sure there's tons of additional stuff you could do. Great work.

The physics make the game frustrating. Even more so, because we see how the game mechanics is solid and could lead to a terrific game, I would definetly keep improving if I were you!

Oh wow, this game had my brain in knots. The slipperiness made it a wee bit too frustrating for my tastes, but the design is really good.

Really clever level design. The movement could be better though, its too slippery.

Nice game! At first I didn't like that the controls were a little slippery but I got used to it while playing.
The graphics are cool, and kudos for the game boy based colors. :)

Now, the level design was awesome! This is were this game really shined. I wish there were more levels, though...
