not bad I like the idea and story but I have come across a bit of a glitch when im playing story mode it wont save my progress after stage 2. if I beat stage 2 then take break and come back im back on stage 2 not stage 3 even if I made it to stage 3's boss before quiting it will do that.
also there is a slight bug on stage 3 where if you clear the oil globs if you land just past them you will still go sliding
