Day 1 is almost over, and I hope everyone's making good progress so far. I've seen a lot of cool stuff already, I can't wait to see what's posted tomorrow.

I've possibly figured out a name for my game, and there's also a gameplay loop. The goal is to dig down as far as you can, while collecting air bubbles along the way so you don't run out of air. When you run out of air, you lose and can reset to try again. I also added the ability to change the color palette, along with some more UI for things like current depth and amount of air remaining. Also just so you know, the plain blocks take one hit to destroy while the rock looking ones take two.

Not sure what else I want to add. Maybe some more sound, or some different tile types. I could add some progression of some sort, but I kinda feel like I just want to keep this as simple as possible.
