The only debuff I got was that the boss became invincable and it was the first thing i ever got and i just tought I softlocked the game but then i did the big spin and never got a debuff again lol.
Haha, but anyway the game was supposed to have at least 3 bosses (just couldn't do it in time), and as it was made with more than 1 boss in mind, even if you got lucky against one boss there would be others to fight and the outcome could be different
