Great thanks! Actually I'm going to add Quest version soon. I use some custom logic for fog and just had no time to implement it in mobile shaders. Yep, enemies are spawning everywhere and the gameplay changes a bit the further you proceed (some other ways of using paper appear). As for "ammo": I wanted to create this old-games gameplay using quick die-learn-retry loop, that's why I removed "ammo" indication and changed some other things :)
Once again thanks!
