I exported the html file to my personal sandbox website where I usually play web games, since i've already gotten 2 viruses thus far. It worked smoothly for me, ok not very smoothly. It was a tiny bit jittery and crashed after 4 minutes. From what I saw, the graphics were decent and the gameplay was great. Perhaps you could make the controls a bit more smooth? Besides that, great job! May I recommend that you create a new project that has a working downloadable file and post it in the comments? Best of luck!
