The concept was original, and the art and music are quite good ^^ !
However, the level design/gameplay is a bit strange (probably due to the time limit ^^).
In the very first level, I'm attacked 3 seconds in, without having the time to read the controls. An "empty" level as tutorial would have been great =).
Then, I don't understand the "Stay" mechanic, is it used anywhere ? That could have been a good element is the level design used that, like buttons that needed to be held down ^^.
The "dig" was not obvious, I had to re-read the tutorial to understand.
Overall, the concept is nice, but I feel like you were short of time for the level design ^^. It's okay, that's the challenge of a 48h game jam, but I'm curious what you could have done with a bit more time =)
