Thanks for the feedback !
Yes, I do plan do precisely add an interaction scene with the Dragon at the end where you can feed her even more and interact with her belly (rub, press and slap), but it's still a lot of work so it will come to the game later. I'll also make her belly react to the player during the main phase of the game.
About the wolf, does it make the game too hard to beat ? I am still trying to balance things correctly (more enemies are also on the way, I am currently working on a bandit girl you can bloat with cake ammo)
