I've seen a few games play with this idea but it's an alright one. I agree with some previous commenters that it might have been both more challenging and more engaging if the timer were a bit shorter. The engine was a little janky and killed me after I completed a level, but obviously, forgivable for a 96-hour solo-developed game. Good job getting something playable together! It's a huge accomplishment to hunker down and make anything at all this fast.
