This is a very nice little game, especially for a first game. Kudos! I really like the art style, especially the adorable little rock creatures. The music and the sound effects were nice, too. There were a couple of times where I found myself getting stuck on objects that I didn't think I should be colliding with; one suggestion might be to make those hitboxes slightly smaller, and/or round off the edges of them if they're squares, to minimize the chance of sticking on them. I also might have liked more of an indication of just how wide a bomb's explosion was going to be before putting it down, so that I could be more confident in where I was placing them. But those are honestly minor critiques. Especially for a first game, this was a really nice, complete game.
Solid work; hopefully we'll be seeing more from you in the future :)
