There is a pretty huge bug where if you die when your die is starting up a power, the die just dissapears. This then causes another bug that if a rocket locks on to you while you don't have a die it stops you from moving or anything that isn't looking around.
Furthermore, getting the power you want is cumbersome, which may be what you want but I just find it annoying. Also, those rockets should burn in hell. I don't know why you added them, but they are the bane of my existence. They made me have to restart twice.
And lastly, some of the puzzles doesn't make sense. Not the bomb ones. Those are clever. I like how you make the eye follow that door up top with lights that way you miss the cracked wall. No, I'm talking about the swapping puzzle. How are you supposed to actually solve it? At first, I just glitched the box on the other side. Then when I had to restart I tried the puzzle again, stuck. I then decided to just jump on the box, jump on the door, and then jump over the little slit above the glass. Either of those doesn't feel like the solution. Your puzzle is so hard/confusing that I found a speedrunning strat before the actual solution. If the actual solution is what I described, then you should make it easier to tell.
I was excited at first, but I feel the game is the equivalent of wading through mud that sometimes doesn't let you move in it. And when you do move in the mud you are not sure how you did.
I know it's a 48 hr game jam for a game that's more about telling you about game design, so I give it 'Cool idea, needs polish' out of 10.
