The tutorial level is by far the best level in this game. It has a big scale, has step-by-step introductions, and the visuals are stunning seeing for the first time.
And what comes after the tutorial level? There are lots of good level designs, but the overall feeling is just a bit off -- Those level designs are not fully presented in the camera, and because the player cannot see what's happening outside the screen, they do not know when to prepare for a slam to destroy the robots.
I would suggest that keep everything else, but zoom out the camera, and give the player some personal abilities that they can perform without the help of energy rings. With this update, I will be able to do much more things inside the game, on top of hit-and-runs. Keep it up!
