The mouse-over select bugged out for me a few times, but all in all a well put together demo I think. You've said a few times you're planning to keep poking away at it, I'm curious to see where you take it!

A fun little demo! The low poly models are really nice, and I really enjoyed finding all the different combinations. Lack of chill tunes & a restart button were a dissapointment though. Reminds me of that old 2048 game. also what is this font? 

Definitely need settings to tone the graphics down. AA, bloom are things I never have on anyway, but this was a little choppy!

Anyway, this looks awesome and I think this would be a great base for a merge game. It already looks similar to Civilisation 2048, for example. Though I think this'd be more suited to a game where you pickup/place the tiles rather than shift them, then like 4 matching tiles automatically goes up a level.

I'm actually not a fan of the focus effect, where you bring the focused tile up and lower the rest. Maybe if this was more subtle, rather than taking everything out of view...

But yeah, really cool, look forward to seeing this evolve!
