Thank you!
It indeed was overscoped for a jam, we initially intended for a boss to spawn after collecting a certain number of posters, and we had an ending cutscene in mind after the boss's death. we even had a ranged attack (where you shoot projectiles that can damage enemies), and a feeding (sucking blood from enemies) mechanic completed!
Not that we couldn't finish the animations in time, no, the animations and assets were completed but we didn't have enough time to add them to the game, so the mechanics were hidden to avoid confusing the players and the boss was removed.
The game was supposed to start with a short tutorial showing you a woman crying in the spotlight (introducing you to the feeding mechanic).
That same woman would become the boss of the game, a vampire hunter seeking revenge!
We are planning to update the game after the jam to include all the intended content!
