Quick dive into making your own sprite-based retro boomer shooter.

Flexible enemies spawner

• Has a trigger to start spawning enemies on player overlap

• Duplicable spawnpoints to spread around the level

• Enter and exit doors to trap and force the player to kill all enemies before being able to progress (optional: there is a version of the spawner without doors)

• Spawns by waves (groups) of enemies. Each group is defined by an enemy class, quantity (number), and a spawning gap (delay until next spawn)

• This enemies spawner is a handful/powerful addition to your level design tool set

• The enemies' spawner is affected by the difficulty of the game as follows:

  - Normal: multiplies the spawner capacity by 1

  - Difficult: -- by 2

  - Hard: -- by 4

  - Epic: -- by 8

• Also, the ammo out of mag capacity for the player and pickups are multiplied the same way; it will take effect after the first ammo pickup or gun pickup you collect

  So, good advice on level design is to put ammo or gun pickups on the way of the player before reaching a heavy enemy spawner

  A unique feature of the BOSS project is that the difficulty of the game is dynamic; you can change the difficulty in the middle of your game, and it will take effect immediately, without needing to start a new game
