Its possible to beat the game but requires very specific builds, the one i found most consistent is body slam maximizing lewdness and stacking the horny debuff on enemies, makes them take stupid amounts of PP
you also can control what the enemy is going to do next via blowjob which can prevent you from taking HP damage against bosses by forcing them to do LP instead, combine that with doze off makes it so that bosses cant do anything against you for the most part
On a side note this is a wild fucking string of words that i never thought would ever be said in my life
