This is a neat little game! I like the idea and the burrowing mechanic is well done. But the controls need some work. I could move and jump with the game pad, but it’s not fully supported. I think using a game pad would work better for a lot of players. Using the keyboard as is is just too difficult.
This game is also very hard and gets hard quickly. At least it did for me. And then there’s all the blind falls/deaths. At least the only penalty is that the game starts you over right away close to where last started making a burrow run.
