Good!

1. On every map, if you went off-screen to the left, about 60% more map was revealed, and each different map had little environmental effects you could activate for an advantage.
2. Every three sectors there was a new map.
3. The skills are explained in a menu option called, "Ninja Scrolls". The title of the skills as you buy them is indeed "Ninja Scrolls", so there is that one. The "Jutsu Orbs" replace your thrown weapon, i.e. your mouse click.
4. I actually agree with you here. There are a lot of gamebreakers, the electro orb most of all, I've found. It doesn't even have a half second of lag time like the SMG.
tl;dr game was too easy. Good, but easy.
