This was a really fun game. There was an odd glitch where I jumped off a wooden platform and went super high and then died. This was on level 3 with the first purple enemies. I played with the touchpad on my laptop (cos I can't find my mouse) and with a bit of settings tweaking got the middle mouse attack working. I like the fact that the enemies change colour and keeping an eye on the top and bottom levels really gets your brain going. I think a time challenge mode could be a cool addition for speedrunning.
