this game is not working in mobile browser

can you modified it

this game is not working in mobile browser

hi bhagya, could you please let me know how you are trying to run this. Its a pretty old code and I need to cross check a lot of things again for tweaking it. I still believe the javascript part would be working for the animation, maybe css part can be modified to fit in the mobile browser.

Can someone help me, i cant run it on my phone. Can someone modify code, im running in html preview, thank you.

the html is more like the js but modified and doesn't work in any sites that i know of

it doest work
