I wish the gradient for turning was lower, it's extremely annoying when one second you move an inch every second then the very next accelerate you can barely stop to move the other direction.

Actually that's not true, the idea that you place template towers then choose a path for each to take is similar to bubble tanks, choosing heavy damage or speed etc.
Finally finished it (achievements-wise), i'd still recommend making your knowledge of coding far more solid, also take a little look at some mechanics, ie making the battles deeper. For example I noticed you can actually lose if you attack some towns when on entirely maxed party/vessel/equipment, just a suggestion - 3/5 overall.
Good concept - learn to code properly before making anything else though, it's full of glitches, if I had a penny for everytime I had to refresh.. i'd have a lot of pennies anyway.
