Sorry to hear the platforming wasn't to your taste. It was intended to evoke a very particular era of PC platforming games from the early-mid 90s (probably most obviously Secret Agent, published by Apogee), and I know that's not going to be everyone's cup of tea! I likely won't go back to tweak it at this point, partly because I think it actually hit its mark pretty well, but mostly to avoid going back forever to old things.
Thanks for the feedback, though; I'll probably make another platformer some day, and based on the response to this one I'll definitely be tuning things differently -- I like fast and nimble platformers too!
