- Removed remnants of Assets/Plugins
- Made a separate Canon weapon for the boss and some separate particle effects to go along with it.
Bullet Spray and Canon Effects
closes #35
- Adds gun spray. Guns can either do a flat spray (for the player) or a circle spray (for bosses).
- Makes the gouts of dirt from canon shot actually go in the right direction.
Pistol Rate of Fire
- Reduces pistol cooldown to 0.2 to make it more useable (still less effective than the assault rifle).
Gameplay Tweaks
- Adds walls in boss test level.
- Moves the position of the boss's canon so that it can shoot in all directions.
- Moved boss to the center of the arena to make better use of the space.
Gameplay Tweaks
- Tweaks damage and rate of fire on assault rifle and pistol to make them both practical options.
- Tweaks health of minions so they can be killed by a single pistol shot.
- Tweaks canon impact to give it a more uniform color and reduce the number of particles.
