I found this game to be really fun at first. It had a charming art style and relaxing music. As the game was from the designer or Portal, I assumed the it would be just as solid and dependable. Sadly, I was disappointed by inconsistant physics and weird behaviour such as any sping jump's momentum being instantly cancelled by pushing an direction on stick (WSAD). This totally arbitrary restriction meant that getting a handle of that aspect of the gameplay was highly frustrating. I see no reason physics or otherwise for it to occur. It made the game incredibly irritating and it never recovered from it. With this knowlege, perhaps you will enjoy the game as I didn't. However, with inconsistent platforming mechanics and thoroughly irritating level deign which punishes platforming slipups to a level which the controls, physics and level design itself cannot justify, I'd have to say, play Portal again. I am, and I am loving every minute of that solidly designed and put together game. I am glad that this game was free.
