This game is susiciously laggy and constantly tries to put itself into fullscreen for some reason
It's not optimized well, and the full sceen was on accident I forgot to change that last second.
But I can give you a link to the flowlab game it may be less laggy

(Unless you are reffering to the movement) if that's the case wait 5-6 second before moving
