@FragFather I ran it again and it seemed to be fine. I change the maximumSpawnTime to 6 instead of 5 since at 5 the enemies like you said spawn at 1,3 seconds. So I thought it could further be made difficult by spawning every 0.5,1 or so. So I played around adding 6 which I think was too much since this time they overlapped a lot since 6 is too high I guess, so what can I do to reduce it to 0.5,1 spawn rate???
P.s thanks so much. Think I finally made progress
