Really Really good game, I can't believe it's a LudumDare game, of course the graphics and sound design are simple (Not that that's a bad thing) but the level design may as well be a masterclass, it gives a lot of room to play with the very balanced drill physics, granted it takes some time to get used to it, and it definitely could use some kind of tutorial level.
I know this is probably just a short project but I feel that it has the potential to become the next super fun and deep speedrunning game with it's unique style and mechanics.
