Fun idea! Physics are kinda jank haha but that's how 48 hour jams go

Physics are pretty janky... if you're supposed to be getting around the map by slingshotting yourself along walls, I have to see it feels more like an exploit than a mechanic. It would be good to teach the player exactly how you want them to use the grappling hook, whether explicitly or implicitly, to make it less frustrating, unless that's what you're going for. Enemy death animation is nice, although gravity for the blobs is broken and it's annoying to die to them and have to start the level again. Some potential in this though.

Nice concept.
The ninja is a litle bit too fast so it is quite hard to control unfortunately :/
With a little bit more of work in the physic, this could be a really great game !

This was fun. mechanics is really well done and nicely polished. ~  Check out my entry when you get time :D

That hook mechanic is really well done and nicely polished, but it feels I don't quite have the reaction time to play this game, since everything is moving a little too fast.

This was fun but kind of hard to figure out how to maneuver.  I struggled to get up to higher places.
