Thank you, really nice to hear that you liked the physics simulation! <3 Yes it does remind one of Control, it might have influenced me subconsciously.
I couldn't figure out how to optimize further in the short time period unfortunately and it currently even lags on the best hardware ^^" sorry about that.
And good point with the total spawn cap and also very good point about how frustrating it is to press ESC expecting a menu to pop up but the game closes -.- didn't think of that :D
