Thanks for your opinion! We kind of drove away from the initial idea, because of the short time. Maybe with some polishing it would be easier and better to play. :)
You're right we didn't consider any checkpoints at first. It was already in the end phase that I realized we should've made some kind of easy mode where each door would have a checkpoint. Unfortunately you can't race time (or rewind it ;) ), so I dropped the whole thing to concentrate on polishing other stuff.
Interesting use of the theme Rewind, the game concept is impressive and I had a lot of fun playing it. The enemies were a bit buggy but overall you've done a great job in a week of time.
Thank you for your feedback! :) Jumping seems to be a serious problem, so I'll try to fix it as soon as possible. When I think about the Z-key now, I realize that it wasn't a good choice of mine. It often has a different position in various keyboard layouts, so I'll consider changing it to Shift.
I'll take a look and adjust the jumping mechanic. It's true, memorizing is an essential part of the game and could be very tricky that's also one of the reasons why we didn't build that many rooms.
