So I have managed to run Linux version by copying pck file from web version game. Linux version has way better performance then Web version. I have noticed that in web version I was not able to turn around on character (on Firefox and Chrome). I hope you will manage to fix these issues soon :)
After all I want to say I like this game. It is challenging, thought the task is simple - but here is the most fun :) Also, from graphical side it looks nice. Having in mind how little time it took to create game it is really great and a fun way to kill 10 minutes :)
