I really like the sound and art design! It's really a delightful game. I just have one criticism about the walljumping mechanic, it counts as a walljump even if I am standing on the ground running towards the wall, which caused some mild inconveniences when I just wanted to jump up and it registered it as a walljump, making me jump backwards! And since the jump is fast and you can hold the spacebar to keep walljumping, sometimes I just pressed my spacebar a little bit too slow and the character counted that as two jumps, if that makes sense, making me lose control of the character a little bit!
Other than that though, I had a lot of fun digging my way through the levels, the digging sound is very satisfying too, and having all those golems following me around is very nice, I love recruiting large amounts of npcs in a game, so that was fun! Good job!
