Slick presentation, and very elegantly designed! My only real complaint is that dying feels very abrupt, I imagine that making the play area just a bit bigger would allow for a more apparent difference between success and failure.
Dully noted, I really had a hard time to make the hole different from the background. The fog helped a lot but I think what the biggest issue is the smoke after the explosion of a bomb hiding the stage for too long. Making the stage bigger would definitely help too.
