Very cool entry for the jam! The pixel art and graphics are amazing and I really liked how you explained the time loop (again, very gorgeous pixel art). The game is really frenetic and had me want to master it, although I do think I would have preferred being allowed to take 3 hits before dying to make it a little easier to get into it and avoid the intial frustration. Also, I would have made the cell door different from standard doors: I thought I had to blow them all up at the start a lost a little time there ^_^’
That being said, this is definitely one of the most interesting entries I’ve seen so far. Good job!
