I like the game, some things I've noticed.
arrow keys with mouse control is really difficult (at least for me)
jumping and moving at the same time doesn't work.
Please take a look at mine (download if possible its less buggy)

Already tried your one, its great, i love the teleport, its a really good idea, idk about the jumping and moving at the same time it works on my end? Maybe its a problem with the web version, will try to fix it.
Thank you for the feedback!
