Hello!
This update introduced below changes and fixes.
Implemented mesh particle system for projectiles. This improved performance significantly. Like 150+ fps with 200 active enemies. (Device - AMD Ryzen 5 5600G, Integrated graphics, 16GB memory)
Increased active enemy count to from 80 to 200.
Changed enemy state computation scripts with more performant one which doesn't require rigidbody 2d or colliders.
Implemented background computation pipe for enemy state and attack calculations
removed spiders for maintenance (sprite sheet re-creation)
Fixed an issue where enemy fireballs keep moving while game is paused
Fixed minor save game issues and script issues
Please let me know your suggestions or issues with the game.
