the html5 version also flashed for me, and I couldn't jump. only then I found there was also a downloadable version. I'd say just keep that. 

the game is good! got more creative than I thought. smoot tutorial, nice use of the shurikens and cool touch with the red legs. 

Thank you ! This may be an issue that occurs with a certain type of graphics card, although I'm not sure at all. Seems like it's something that comes from the engine itself...
