Pretty interesting game! Gotta say, while I enjoyed my time with the wackiness of it all, it was a bit rough for me in some respects.
First off, my introduction to the game was a bit confused. My impression was that it seemed like the game had a big focus on combat and platforming, what with the cool introduction of your transformation powers, and I gotta say it felt satisfying to get that vampire combo off on the stompos what with the cool hitfreeze it had! Because of that, I didn't quite like just how many characters there were to talk to: felt like it just kept constantly stopping the pace of combat and platforming to talk to so many people and their goofball nonsense. I just wanted to get to the action! Don't get me wrong, I love the characters and all the charming quirky expressions and dialogue they bring: I just didn't realize that the game was actually all about talking to them for fun and hints and going on a scavenger hunt. Once I realized that, then I was on board and everything was quite the fun adventure! It's definitely partially my fault for making weird assumptions, but perhaps the game could also be directed in such a way at the intro to let you know what you're in for more accurately (heck, maybe combat isn't even necessary for a game like this?)
In terms of other feedback, I did feel like the movement of the character was a bit...I'm not sure, just felt a bit wonky: in particular I think the character felt overly heavy due to the lack of hangtime for their jumps, which made double jumping annoying to time. Also, for such a cheery game, I was surprised at how unbelievably punishing it could be: I spent so much time collecting practically everything only to die from an off-screen shot and have to start all over! It didn't exactly make me want to start it all over, but credit where its due, the game is charming and cute enough that I think I will get right back in there and find out what sort of characters are left to find and gab it up with!
