thank you! i used the add point func of Line2d and limited it to 30 points, btw the plyer doesn't move vertically , so i change the points on every frame .
unfortunatly i couldn't play your game on my browser
Thanks for explanation. I see you took similar approach with not moving the player :)
I tried playing in Chrome and Firefox and didn't have any problems. Didn't try other browsers though. I've uploaded exports for Windows 64bit, Linux 64bit and Mac OS X now as well. Hopefully you will be able to play it.
