That was very fun great for just one day

I like this one. It's oddly compelling.

I agree with @hanoth, oddly compelling. Nice music, too.

It seemed very easy to get lots of score. Fun music, I like the whole look and feel, very late 70's...

This was a lot of fun, and the music is pretty catchy.

What would make it better? I wonder if it might be possible to add a bigger "risk vs reward" element - whether some type of blocks (or maybe the big groups of the same-colored blocks) could take longer to drill through (and so use more oxygen) but give bigger points.

I could also imagine simultaneous multi-player on the same map could be interesting!

Good work for just one day!

Pretty good fun :) Nice graphics and sfx's, wouldn't take too much to turn into a full on game :)

FUN!

Step 1: Put on mobile app store.
Step 2: Profit.

This game is a winner. (Although in its current form it's probably too easy. Adding in buried land mines or something to avoid would bring this to another level.)

I am not so sure what I am supposed to do. Not even sure whether I am doing well or not. But the style and music are cool. Might need some kind of feedback on how well one is doing.

For just a day it was actually pretty good. Too bad you didn't have the time to tweak the difficulty/scoring enough for the game to be challenging.

This would make a decent Mobile game.

Fun and pretty addictive drilling game! Level 26 and 1030300 score. Quite literally needs more things that either slow you down or kill you, now it's mostly just drilling down constantly and occasionally sideways for oxygen. Still fun though! :)

Oh and you need to upload source if you want to be marked in the Compo.

felt laggy but was a very nice little game. Did enjoy.

Thanks for all the feedbacks. I've just uploaded my sources. I agree with you all, this game is missing of too many things, so I will keep working on it, on my free time.

Awesome concept! Really fun to play.

The web version wouldn't load for me :(

Doesn't load :/

Ok ok just see that! I am on it!

I enjoyed this one. :)

Since my server didn't support to many connections somehow... I've uploaded the game on Gamejolt.

Addictive and fun.

This is fun, but I'm pretty sure I could play this indefinitely by holding down and sweeping left-right for oxygen tanks. Maybe throw in some kind of barrier that forces the player to get a certain combo/score before they can proceed down?

I really liked this. A really satisfying sound when you drill a block.

had fun playing it, only wish there was more diversity and required a bit more thinking, but for one day, amazing.

Fun right away! My favorite kind! Great job.

Might wanna swap out controls for WASD -- the page kept scrolling while I played.

Great little casual game. I died a lot at first but it's true that once you figure it out it becomes a bit too easy. That could be fixed easily by adding more elements, and as it is it's a great game for one day.
My only complaint is that using the up or down arrows too much made the actual page scroll (using Chrome on OS X).
I agree with quill18 that this game has a lot of potential on mobile. Well done!

wait, is that Mr. Driller? Nice job creating a (more fun) clone of it, though I'd prefer to see more mechanics on the game.

(Actually my game was inspired by it too)
