This is a really nice game! It took me a second to figure it out as I was expecting to be able to use the unit's abilities the moment I stepped into them, but after a few rounds I realized I had to wait for the host's turn to make them act. I would definitely play this game if it were fleshed out more, such as more levels (there's only the one, right?), being able to move the controlled units, controlling weakened enemies, and having to deal with more complex threats.
I did find out that the logic which blocks you from attacking when you run out of APs doesn't work right and you can just spam attacks on enemies until they die, but that doesn't seem like too hard of a bug to fix.
Awesome job!
