Polished, semi-futuristic, non-bullet hell with ship upgrades. The best i found would be AirAttack 2 but it fails to grab me because of the whole WW style. Some other examples i have already tried and left: Apocalypse Mewow (great but left in the middle) Icarus-X (nausea backgrounds) AeroStrike (way too bland backgrounds) Hawk Squadron (good but way too F2P after stage 10) Dragon Heroes (Galaga style enemies) Bullet Hell Monday and Phoenix 2 (great but way too bullet hell for me)
