Needs multiplayer. And a badge. And team selections. I'd really like to try taking on 4 bots. :)
Add these things, as well as Lives objectives, and this game will be perfect.
As it stands, 4/5.
I like this game quite a bit. The only problem I have with it is how slow the battles can be.
There should just be an auto-battle command for when the fight is so one-sided that it's certain that you'll win.
Overall, it's a fun game.
