This is a really good game!
I really like the audiovisual side of this game; the combination of pixelart graphics, with a calm music playing in the background, creates an image of a cute platform game, which in my opinion, works great!
The game mechanics, controls, and levels design, are also very well done. Perhaps the game mechanics aren't too innovative, because they are similar to those in Braid, but still, they have been implemented well, are easy to understand, and using the time leaps feels great! Levels themselves, aren't too hard nor easy, and mostly require good timing rather than a good tactic. There were few places where I got stuck for a short bit though, but solving these issues felt satisfying.
The only issue I had with this game, is that it's a bit too short. After some level, the game putted me into main menu, and choosing the continue option, sent me back to that level. Levels are fine, but there could be more of them
All in all, this is a very well made game, that looks, sounds, and plays great!
