Thanks for the feedback !
Concerning melee, I'm not too hot on the idea of completely aiming attacks, it still needs some degree of snapping. But I'll agree with you that it is a little too generous right now.
As for spawning enemies, the demo is limited to 5 instances of each enemy. There's not much of a point to more of them, and most importantly they're pooled now instead of being spawned. But I'm not sure how you got only 3 spawns since it should go back to 5 if you put more, I tried to replicate that but to no avail.
