Ha! Yeah.. so we originally planned on doing a bit of a tower defense which then turned into having you manually control the turrets after some discussion. The goal was to have it be a frantic sort of game where you do upgrade mid-battle but a tutorial screen or better onboarding would've helped a ton in explaining this. The end result is honestly a mixture of our original plan + a lot of scope cutting due to time limitations.
Damage type is very important to winning (along with the calldowns which are the bottom 4 upgrades)
Laser = Bonus damage against the drones
Missile = Bonus damage against the bombers (bigger dudes)
Turret = Bonus damage against the small guys
Thanks for playing!
