Hey, have you tried to move with holding Space + WASD to move inside the grave? I can update the description for Controls if it's not clear. If that works please let me know as I was offered to upload the fix on the original game page.
I see! :D Yes , that's my bad, that works, I didn't see that in the description. I really like that minigame, that's very well executed, pulling back an item feels really smooth!
