This is incredibly dull, especially because of the obnoxiously slow movement speed. On top of that, the puzzles aren't very hard, making this entire game seem like a bland advertisement thanks to the ending.
Super tanks are a little OP. Their range makes them able to take out defenses without even trying - lower their range, and they'll be much more well-balanced.
Have you tried using the artillery towers? They have the same range when fully upgraded, and a single artillery artillery tower should be able to take out a super tank. Also remember that super tanks cost 2000, so you have to have pretty good defenses or armies to take out a single one.
Buggy as ding dong. The character control is completely blasted. No, I do not want to do melee damage! No, I do not feel like firing instead of reloading. No, I do not feel like firing regularly instead of using a skill. I'M THE BOSS OF YOU, GET IT ALREADY! > : O
