I love metroidvania games, glad to see your entry!
The time rewind animation after death was cool. You had a lot of levels and different challenges. Some things you could improve is the controls and the map awareness. I kept hitting on the ceiling when jumping, and it was hard to attack enemies who were above of me. About the map awareness, i think it would look cool to have a clearer distinction between the zones and maybe a map of the zones you have already discovered.
Well done, looking forward to see more!
Cheers!
