I never managed to make web conversions of my games. For now they all are: download, unzip, play. No install ! To remove the game, just delete its folder.
Yeah, that's how Bouncenoid works as well for desktop, download, unzip and play. But several people told me they either don't want to download the game or they don't own a PC or their PC is a work PC and they're not allowed to download anything... that's why I got into the troubles of going web. Thanks for the reply, I'll check out your games if I can.
