I might have broken your game lol
You actually got the energy build working! Wasn't able to do it myself since it requires quite of a bit of luck to get it started, but that's alot of damage and energy, cool to see the build works but need to balance it to make it more fair and consistent, thanks for showing.
I like how it eventually gave up on trying to display the numbers for damage and just switched to "infinity" lol.
Sadly it slowed down to a crawl in later waves and eventually crashed at around wave 105.
