It’s a bird! It’s a plane! …it’s a bunch of spy drones!? The purple republic has sent drones to spy on the scratch united association! Don’t let them get through, or the purple republic will be able to destroy your secret hideout! How it works: The higher the level, the easier it is. Level 1 is the enemy’s all out attack, and when you beat it consider the game to be won. Q: what’s “penalty”? A: when you progress, some enemies are guaranteed to slip through cracks, so you gain penalty. +1 for letting an enemy get away, and +5 for every friendly that hits the ground (after being shot) Q: I get penalty for hitting them!!! A: no you don’t, penalty is counted if they hit the left side, even if they’re crashing. However, the level 90 special ability just nukes them and they can’t escape. Also, friendlies are immune to it.
This took great inspiration from Atari’s “Missile command” where you try to intercept enemy bombers in a battle to protect your home. This game takes a similar approach, but uses my terrain generation system to give you a different experience every time.
