This game was really fun, it was just so satisfying to keep digging with the music and the sound effects and beautiuful, I really like that it goes 2d 3d 2d when we switch layers it's a really nice looking transition. I think if you tweaked this game just in some ways it could make for a really good mobile game.
Some feedback: I think it was a bit boring in the beginning just digging one tile at a time I think you could have made it harder earlier. 2) I think an enemy type that would really woork here is one you need to take a turn to hit so you can kill them. Or maybe having that possibility for all enemies, idk. 3) The slime and the skeleton seem to functionally be the same enemy to me, variation would be nice. 4) If there could be text that said whhat the items do when you hover them. Really well made game man, hard to believe this is your first game jam.
