I think there are a few things to love in this game:
1) Very good mechanics, It's not the best but the controls feel tight enough to play the platforming well.
2) Very nice time rewind implementation - I think your game has pretty good implementation with the theme, having time rewind falling platforms literally or time rewind between timelines - and your trasition for that is pretty good.
Otherwise I thnk there are a few issues with just level design, and the gameplay with the final boss. Other notable things - but understandably lacking due to limited time is the sound and graphics but I think it's pretty cool.
It's one of those solid 5/10 games - it's not the best but I'm sure with work, you can definitely round up the game with good polish and bring it to a nice fidelity!
