As everyone else already mentioned here the game is insanely difficult, and while that can be a good thing here it felt a bit unfair as you had to balance the challenging platforming with the slow-mo mechanic. It would've been great if you knew how much more you had to go before the next stop watch or even better a checkpoint so you wouldn't have to start from the very beginning every time. That way players would be more compelled to finish the game.
Other than that the controls are tight, main mechanic engaging and I really liked the music effect, good job
