Nice puzzle platformer. I didn't even realise the first time I played it that I was meant to collect the bolts AFTER the key haha; when I read that I went back and did it again haha. I of course died a bunch of times then, and I'm not sure I'm keen enough to go back and try to do a perfect run haha. I'm content with my knowledge that life is meaningless :P (haha it got very existential at the end there which vibed well with me haha).
Overall quite solid! I dont have too much to complain about with the game, everything was fairly decent, but I guess everything could be bumped up slightly too in terms of graphics/sound effects etc. (everything was good but not great I guess is the best explanation I could give; but that's understandable for a game-jam game i think)
Only thing I thought could be improved upon a bit more was the theme; I didn't fully understand why the key 'rewound time', or why rewinding time made certain platforms disappear/appear, or why I was collecting bolts. But perhaps some things are just not meant to be understood (or perhaps I would have understood more if I did that perfect run through?).
