Wow, this is truly impressive! A nice mix of various genre types, I especially enjoy the Vampire Survivor-esque auto-shooting paired with a platformer. I would recommend working on balancing the weapons a bit better, as I couldn't make much progress at all with the melee weapons. And adding additional enemy types, or changing up the level layout over time would go a long way. But overall, incredible work! I can see this being expanded into a really great full game!
