I thought this did have some pretty good ideas, but there was one major thing against it. The graphics weren't that good at all. It's because you just fought the same enemies and the lines and shadings were pretty bad. It's a pity, because there really are some good ideas being presented here. The best is probably how you get to count down the number of hits it takes to kill a robot. I didn't need to take the tutorial.
It's pretty easy to understand. I just think there should be more detail, like maybe have the player go into different places instead of just the same area for the same level. It gets a little montonous. It's still presented in a nice and clear cut manner. The upgrades are good too.
