It's pretty, but a game is supposed to be fun, not annoying. Way too much has to be redone, slowly crawling back to the start for way too many jumps to retry, any time any 1 of these jumps is failed. Double jumps, actually. Double jumps are useless, clunky, and ugly. Single jumps would be a better idea. They would bring some much needed energy and flow. Difficult shouldn't mean tedious. Cheers....
