this is definitely one of the better games factory 2 games ive seen lately, i do agree that it does, seem to hamper the experience with slight lag, you also have problems with random enemies disappearing into the abyss, i suggest in the future to use, flash for making flash games, no games factory :)
the art also needs improvement, it seems to be lacking and the black and white dont seem to engage the viewer too well. so you've got room for improvement.
i suggest you collaborate with someone next time on the art while you work your way through the coding and design....
This crapventure is indeed, crap. Seriously. All you do is avoid the creatures (which have unfortunate placement parameters) and get the, collectibles. Then leave.
