A fun platforming gauntlet, and then a challenging point-defense segment. I really enjoyed playing this game, and found it pretty easy to get a hang of the "slingshot" mechanic, which is a pretty neat way of getting around. The problem with it is that flinging yourself into enemies to attack them isn't really effective. The enemies like to bunch up, and launching into them only kills one at a time, so it's hard not to take damage.
Also, a small nitpick: I didn't really use the dash ability much, since the slingshot feels like a "better dash".
