Wow! Lots of things to love about this game - I think your game was one of the more inventive ones in terms of the theme, really bringing out the metroidvania exploration genres with a unique time-rewind twist! I got kinda stuck at one point after getting the jetpack so I didnt finish it.
The music stood out to me, the fact that it changed between different sectors, even by a tiny bit, adds a lot to the immersion and character of each sector! Loved that!
The controls actually feel quite good despite the fact that you have so much controls and things working together at the same time. Love it! Very smooth and responsive.
