In the PC version, from the 20th wave on, the fps dropped to 3 or 4, there are too many items on screen. I think more than just enemies are the energy items.
Got a max of 27k points max.
Impressive! if you hadn't commented, I wouldn't have known that it was possible to play beyond 3k.
I only played seriously myself in the browser, and by 3k points the screen was fully loaded with enemies and laggy as hell.
Thank you very much!!!
