Overall pretty good. Some puzzles could be cheesed, and I found occasional bugginess with re spawning. It wasn't clear at the very start how the time mechanic worked but I eventually figured out that it was on a gauge. I think a way to improve the time mechanic would be to have it passively regen instead of being as a pickup. Cause often I'd find myself lacking health or ammo but not rewind, but I kept getting rewinds.
