Given that I accomplished shrinking size of my project and with huge help here and on arduino stack exchange, basically rewrited to atmel studio, my "fire cat" displays all(but 1 led, this was problem before idk, sometimes works sometimes not, not that big of a problem) leds, problem now is I have a button connected on Attiny13a PB3, in theory and simulator everything works, but then IRL it doesnt, like it cant even read the f*in pin
