Thank you very much for playing the game and for the video feedback! Very cool! I'm sorry that it crash.
It happens to me with WebGL games too, it's strange. Now at this moment I'm sorry that I didn't upload the installable version... Lesson learned for the future. :) When a game crash, I close the browser application (firefox) and reopen it, that's how I solve it, if I just reload the page... the error remains... I don't know why. :) I wish you all the best!
