I couldn't finish your game. I encountered this weird bug that didn't allow me to proceed further. I retried a few times and everything was the same. Sorry, but i just couldn't do anything.
But i'll try to review this game from what i've seen (1st level). First of all, it's really good. Music is nice and relaxing, controls are responsive, tutorial is clear and really explains how the game works, time stop mechanic is a nice addition as well. I'd love to finish the game, but yeah... Anyway, thanks for your submission, i'll try to complete the game again for sure!
