Still working on Tank!Tank!Tank!. The game is still fun overall, as I sort through the various tanks, trying to figure out which ones I like best.
It sounds like a good idea, but I actually don't care for the fact that you have to level up your tanks to gain access to their best (true) forms. It makes s-ranking stages more work (since you need optimal tanks to do the job on many stages), and forces you to manage the experience points wisely (since for some reason, you lose any experience after a level up; say you only need 50 experience to the next level, and the stage you're on gives 500 experience - you lose the 450 experience difference!).
