Congrats on finishing your jam game!
Your core design here doesn't feel that fleshed out. You're destroying the terrain without much reason. But I think that's okay. This seems more like a meditative, stress reliever than an actual 'game with an ending' type thing. It would have been nice to have a target score, or end flag/goal/area to reach, but it works. Nicely done.
The real winner here is that music. It's delightfully absurd and strongly reminds me of Ween. Please please PLEASE upload that song somewhere where we can listen to it and share it because it's beautiful. Well done.
Good job on your game. Keep making games!
