Thanks so much for the feedback its really helpful, just some follow questions so I can improve on your points!
What you mean the rush by chance? I would to capture that, but unsure what you mean by that!I read your comment wrong lol- Def a good amount of enemies can lag the game, by chance do you recall around how long it took or how many floating red things there were when that starts to happen?
Also did some experimenting and I think I think I know what is going on with the lag! I believe its the hit stop that occurs due to a time delay. When vsync is not enabled or supported it does the intense game lag you are referring to! I managed to get that on my machine, and that is totally not intended and I will patch that up.
