Thanks a lot for the detailed feedback! The lightning chain performance issue is definitely something I need to fix, especially because the late game is supposed to get chaotic without killing the framerate.
I’ll also take a look at the projectile readability, moving the stats, and adding upgrade descriptions to the pause/menu screen. Those are all really useful suggestions.
Really glad you enjoyed the core loop, and thanks for taking the time to test it!
See you in the next update!
