8 hours, pick ups and gun two.
Gave the player projectile a better shape and a material so people stop giggling about firing tennis balls. Matched ineffective hit particle colors to new material. Fixed pick ups causing a double increment due to looking for overlap. Turret spawn displacement places objects a fixed distance from the ground to prevent planting walkers. Pick ups being held in place by a single walker can still be turned into turrets but it takes longer. Additional walkers decrease time to build multiplicatively. Removing a building walker reduces progress. Progress lost if no touching walkers. Gun 2 burst projectile is a slow moving large orb that doesn't get blocked, dolls out a total of damage before destroying itself or lives a fixed amount of time. To make this work with buildings, only damaging vulnerabilities, implemented a new collision type. Balanced health values. Tightened up opening phases.
