Had fun beating this lil' game with everything on par, and even finding ways to do a ton of them under par! (Hint: You gotta use jumping to your advantage). Your cuts have to be very precise and well placed, and you guys milked the mechanics really well for their usages. Would've been nice to have more mechanics and more levels though; maybe more focus on the platforming element as well as the cutting strategies. My last complaint, as far as mechanics goes, is a lack of visible achievement for aforementioned under-par level victories.
As for the aesthetics: I really enjoyed the music! It's simple, but a nice listen: I haven't gotten tired of it still! The art for the platforms is well done as well. I would've liked an animation or something for the ninja cutting space though, and the ninja himself is nicely done but perhaps just not that great in my opinion, he blinks too much, his walk animation is a bit boring but functional. Also noticed a bug where if you walked into a laser the walk sounds still play until time reverses. His jump is really cute though, haha! Makes sense this fat lil' ninja sucks at jumping too, considering he can just move space around and stuff in order to get to where he needs to go.
Whelp, that's my two cents. Hope you guys update it, or make a sequel!
