Unfortunately hard to impossible to control, at least for me (Web, Chrome, no GPU). But I love the story, basically the same that I chose :-)

Ok, I tested again. First of all I was mistaken, it was Firefox, not Chrome. In Firefox, the game starts in a bigger window and then the gameplay is hanging. Same for full screen. In Chrome there is no separate window and no full screen option and the game runs well. Same in Firefox if you reduce the window size.
When the game runs, it is actually a fun rage platformer, well done! :-)
