two things, one it has some bugs but as a developer I don't expect there to be none(if I pressed esc before touching the start checkpoint I spawned at another checkpoint and if I dashed into a wall it would stop letting me move until I dashed again)
and second, could you make w a jump button option as well(it is ok if you do not), this is because I am terrible at 2d platformers with space bar jump.
Anyway, I love this game and will definitely follow its development.
