What I liked:

Great audio, beautiful music. The graphic effects and lightning were also very pretty. The sprites themselves could be better but they were ok. It's fun exploring the map. The dash mechanic was cool. 

What I didn't like:

Fighting enemies was not very fun for me so I just played it kinda like a stealth game and tried to get past them without killing them. The rewind mechanic only got me killed when I tried to use it, because enemies can still hit you while you're going backwards. And also you can't go backwards too much. So I didn't use it much... One time I got killed and the camera went to the respawn point but I didn't respawn. Also having a pause menu would be nice.
