Thank you :)
Yea, I´m aware of the performance issues - I did limit(and later disable) the normal white damage numbers, but forgot the crit numbers, which eat even more frames because of the rainbow effect. And at some point the player will have 100%+ crit chance.
I will do at least one more patch after the jam is over to counter this. Maybe make the max count of damage numbers FPS dependent or something similar.
