So a bit of lore behind the fight. _____________________________________________ (no mercy route) So Flowey saw that you were a serious threat, so he never showed up to explain his backstory. Instead, he was explaining the situation to Asgore. Asgore gave Flowey the 6 human souls, and his own soul so that Flowey could hold his Asriel form for a while, and hopefully stand a chance against you. _____________________________________________
(also guys, warning: there are a few bugs. *on the "Star Blazing" attacks, if you're against the right corner before it shrinks to normal size, you'll be stuck outside the box until the end of the turn. *the left side of the box can sometimes stick you to it. idk why, but just move the other direction to fix it *the KR attacks can eat a HUGE chunk of your health if it deactivates when you have it so be careful *thats the main three i found, i patched most other ones i found but lemme know if anymore are found.) ALso, warning: this fight is pretty dang tough, so don't get too upset, alright?
