Really good game!! The movement is so smooth and feels nice! I think the difficulty is okay as well. As a suggestion, in one run I died because I touched a breakable platform and fell, and then I wasn't able to continue going up because that platform didn't respawn. Maybe a respawn after a few seconds would be nice for the game.
The rest is really good, nothing to say. The drill mechanic is amazing too! Congratulations on making this game ♥
