The game is not a demo, Unity web player does not support custom headers so the online competitions are only available in mobile and standalone versions. Practice mode is available in the web player.
Hey, it's not lame. We have best graphics, strong server to host quite a big amount of players at once and other notable things. We release updates monthly. Besides, half of our TOP100 players didn't pay a single dollar.
Could you please give more details? Heat distribution is not even in some situations, but not all units give heat out. Basically to share heat very well, you would need exchangers that do this. Otherwise cells just put all the heat into tiles next to them and that is it.
Thank you for your comment and taking the time to rate the game!
