This is a web-native game, so there isn't really a downloadable version, sorry! I could give you a download of the files, but you'd need to host them on a local server in order to play.
You could do that for us, having local server, could also mean advertisement and possibility for co-op and multiplayer and chat ideas in the future, maybe a split screen where 2 players can place tiles fastest and get bonus points and having a ranking structure. Lots of potential for certain here in this game.
