Cool game, looks great visually! I think music would really improve the experience of this game. The fact that turns are slow, there's no music and enemies that aren't connected to you don't really do anything makes it a bit boring. There is a bug if you end your turn while a unit is selected, it will still show the possible places to move to and attack. Esc to deselect doesn't work well when that's also the key to exit fullscreen in my browser.
There's great ideas here, but the execution has to be improved upon, as some other commenters have noted as well.
