I’m finally managing to get basic game-ish features working in ECS, and my Platforming/AI manager still maintain above well above 60fps even with 500 NPCs chasing your butt.  
It’s down to 20 NPCs in the demo, ‘cause otherwise it’s physically impossible to pass through the hub area, unless you manage to ride the wave of bodies throwing themselves at you.
 
Demo 0002 is here (130Mo).  
There is nothing super interesting in it, it’s more of a “I’m not dead” update.  
It’s compiled with a lot stabler version of Unity, so for the people who had crashes with the previous version, please give this one a try.
 
Controls :  
WASD : Forward/Backward/Turning (it’s tank control for now, will change later)  
Space : Jump  
Shift : Sprint  
Escape : Quit the game
 
Dev Controls :  
Home : Teleport back to spawn point (in case you fell into the void or get stuck)  
End : Stop your momentum (in case you put yourself on orbital trajectory by going too fast and jumping too high)  
Insert : God mode (NPCs difficulty isn’t really tuned)
 
Right now I’m still hesitating on the final gameplay.  
I wanted to make a platform/rpg, but the ability to have hundreds of NPCs fighting at the same time seem too good to not use.  
But going for a Dynasty Warrior / City of Heroes’ Mastermind gameplay would kinda clash with platforming since it’s the kind of thing that require not having a bajillon NPCs around you.  
So dunno, gonna have to think a lot more about it.
