I playtested all of my versions and every windows version was playeble for me.
Also the newest browser and the newest windows version are the same except for one bool that tells the game if is for winodws or webgl.
I had to limit the movement because if i made the player move freely than you could easily dodge every falling guy because there is enough space in between them.But i made the cooldown pretty small so if you press the keys fast enough you wont notice how slow it is.
But thanks for playing it and the long comment :)
