If you make a sequal, consider making it so that you could customize what weapons the bots you make use, but in exchange, decrease the accuracy and damage inflicted. Also, fully upgraded cutting lasers are OP LIKE A BOSS!
This game is suprisingly fun. Though the fact that the lasers move closer together kinda makes it pointlessly more difficult when you have the treadmill and wind working against you in addition to the spike balls.
This was an amazing visual novel with an equally good story, but the only real down side that I can see to it is that it was short. That and a few spelling mistakes, but I'm not a spelling nazi so I won't worry about it.
