Performance issues have never been reported, and i've done tests with 250+ clones onscreen and seen no hit. They cull. i dont know whats up with your PC but its not my game's fault. it runs without lag in browser on my chromebook, which is,,,, a chromebook.
everything else you've mentioned has been fixed.
about half of the winning games of this jam are batshit insane choices. it's obvious to everyone who isnt a pirate sycophant.
