This is a really fun game ! I really appreciate it !
But. There is lot of mistake with programming and game design ;(
In about 10 minutes of play the game start to lag a lot ! I was forced to quit and reopen, probably because you was exploring too much terran, and rendering all in the same time may cause optimization lag (maybe) a good thing could be to only activate square that are maximum 10 squares away of the player.
And then the major problem is the game design. We don't know when we select a spell, we do it randomly sometimes, you should show the range of the spell more clarifying by make a color or something.
It's what i do in my games. Emulp if you want to see.
And give more spell point.
But yeah that's a great game !
