Cool game! I love the art style, especially the little dude. Movement feels pretty sluggish and clunky tho, especially getting stuck on some corners. The speed upgrade helps but also makes me feel like there shouldn't be a speed upgrade, and you should just start with that as base speed. Probably for progression sake, but still feels kind of bad. The digging is such a cool mechanic, especially with how the dirt works, but is a bit too slow to feel as fun as it could be.
Great job overall!
