Definitely fun, but I noticed multiple times where I really wished there was coyote time (essentially a grace period where you can jump after walking off a platform). The boost occassionally made up for it. That being said, if you're going for ultra-punishing platforming, who cares? No coyote time for the noobs! Just depends what you're going for :)
Also was there supposed to be no audio? Or was something wrong on my end?
