Wow, what a great game. I'm glad I got it for free. I would totally buy a longer and more refined version of this for, like, 20-30 bucks. I have a few small gripes with the game (like how the centipede isn't really introduced with any buildup, the seeming inconsistency of the grapple hook's throw, or the repeated use of the same texture), but overall I'd rate this a solid 7/10 game (on a more biased scale, I'd probably say 8/10 or 9/10). Definitely worth playing, definitely worth beating.
