Random colors would of been fun. Also coloring is the funnest part of the game, instead of punishing us for using it we should get a higher score the more we uncover.
The beginning of the game needs better instructions. I had no idea how to save and I almost won my first battle and tried to have a character with low HP flee only to find out the whole party flees. The in game help was of no help with this info.
You can glide forever on stage 1 if you buy everything except an engine. Just hold right until your velocity reaches 0 then hold left, you will shoot up and keep repeating. Try it out and vote up if it works!
