The mood is on-point and the dialogues are devil-icious-ly funny. Also, you made a complete game with different endings, that’s a hell (pun very much intended) of an achievement for a jam! If you’re looking to keep working on the game, I would start with fixing the collisions as it would greatly improve the gameplay. A bug-free version of this game would be super appealing.
I would also recommend trying to keep the pixel density consistent in your art. For instance, you used bigger pixels for the background, and smaller pixels for the characters, which is something that pixel artists tend to avoid. While this is of course subjective and there are no hard and fast rules, the overall consensus is that, if you’re looking for a slicker, more polished retro look, having the same pixel density (or “pixel-size”) for all your sprites is preferred
