Incredibly fun game with no cruft. Took about 24 hours to get 83% completion. Might poke around for a couple other things, but I'm very satisfied and have no desire to collect every little thing.

Edit: spent 2 more hours and got to 90% which is everything worth doing as far as i can tell. there's one aggressive jump/dodge psycho puzzle room that i might take care of out of spite but yeah. good game, meh story, mostly garbage collectibles but generally the boring crap isn't behind a wild sequence of violence.
