Frustrating
It's not a bad game, and I think it could be really good, but it's far too hard, even playing as defensively as possible they still get through because the shield is just too small, and their attacks always do at least twice as much damage as mine. I just can't figure out why, I'm sure I'm doing pretty much the same thing as the enemy.
Movement is too slow when you are defending, they can always get through, but they seem to be able to get back and defend easily. It doesn't feel like an even game. Maybe I'm just shit at it, but it's really frustrating when you lose after about 3 attacks, when it takes about twice that to kill the enemy, even with powerups!
