Thanks Ill cut the resolution down to 720p its meant to be played at full screen though, there's a button at the bottom right to go full screen.

Where exactly does it crash?? If you mean it freezes thats just you running out of time, you can still hold shift at that point to rewind.

I should probobly add an indicator

Just checked out you game. I gives off a Contra vibe. But I dont understand how it matches the rewind Theme

You can rewind time even if you die. Im glad im getting this feedback. Ill add an indicator whenever you die
