Truly amazing first submission ;)
It's really hard to get anything done on a first gamejam and you managed to make a great art and impressive scripting as for a beginner.
Let's me get to criticizing then, as I'm best at it :P
Game Design & Fun:
I enjoyed the levels. There are parts that require some precision, so it wasn't always easy to get to an end, which is good :P
Innovation:
I believe the idea with rewinding time to get to previous positions will be really popular on this jam, but apart from that I really enjoyed that you've connected it with a really nice atmosphere that makes it unique.
Theme:
There is obvious connection to the theme, but I've missed one thing. I wished there were more levels that required our ability to beat, for example with buttons (I get that there was prob not enough time for that), but apart from that, it's good :)
Graphics:
They are just marvelous. Good use of paralax, nice glow and only thing I could critisize is the slowmo being laggy. If you made that smooth, it would be perfect.
Audio:
Ofc it is good xD
