It is a game you have to get used to (controls etc.) but it is nice. Guess it helped to have played it on Steam too as the level I was stuck on suddenly became easy. Music also nice.
But it has this "exception on WebGL" issue. I played on Firefox and got it after level 26 and prior to level 27, crashing/freezing the game and forcing a refresh. But after 40 minutes and some refreshes, I was lucky to avoid the issue.
