Two things that don't work:
a) If you equip Ionic Shield on a unit with Armor, Armor works, but Perfect Armor from Ionic doesn't (unit still receives combat damage, reduced by normal Armor's rank).
b) Stage 143 has you start with 2 stars, and finishing it within a few turns with full life and huge damage to opp shows your progress bar on somwhere around 2/3rds towards 3 stars. That can't be intended that way, can it?
Can you somehow disable collision between your raiders, so the soldiers don't constantly shove the archers towards the enemy by running back and forth?
Most important feature I would want would be changing ship deployment order. As is, the ships are deployed in order you acquired them, but I prefer to split them in heavy and support groups, which means filtering through the row of ships and spending the first minute of combat trying to group them. Would really help if you could do that BEFORE battle.
Sheep gun!?! Kappa shells? Riot shield "Shields are not in this game"? LOVE IT! This game has quite a few easter eggs for being just a 2D shooter. Alas, the performance suffers despite minimal graphics, which is surprising, since my comp runs stuff like Borderlands 2 flawlessly.
