1)
@Bex suggestion to play it on android only works as long as it is not an encrypted and packaged game, because with encryption you'll need the official player and can't bypass it with the index.html
Exe's for windows don't work on android - it has to be deployed to android to be able to be played there.
2) Android has a lot less resources than a full computer. It is rather easy to create a game that cannot be played on android even if it is good on a full computer.
For example size of parallax maps: with most android devices, maximum parallax is somewhere 30x30 tiles, with high-end devices possibly bein able to handle a 50x50 map as maximum.
A full computer can easily handle a 100x100 parallax map, with high-end-devices and good game developers making 150x150 or greater maps possible.
So it might simply be impossible to deploy that game to android.
