Really like it.
First of all, i like a lot the characters and the illustrations, reminds me a lot of the Shin Megami Tensei serie, especially the Nocturne one. :)
The gameplay is simple, and once you got the habit the game it's not impossible, if not easy. The self-healing enemies are simple to kill, you guys just defend till you have enough points to execute some attacks of a type your opponent is Normal or Weak to, and you're done.
Started with Yaksa and i think he's the strongest among all the starters. :)
4/5. With a bit less pixel-ated graphics and some little corrections around, this would deserve a 5. Hope to see a sequel. ;D
