Congrats on completing the jam! Very cute game - definitely gives off the Banjo Kazooie vibes you were looking for! Very impressed that you got this much done during the jam - 3D and a 3D platformer at that is very hard! Unfortunately I don't know anything about John Wick so I couldn't get any of the references - if there were any.
Level Design Feedback - Some of the terrain was difficult to navigate with the controls - ex. bookshelf. I also feel like you don't need to rely on floating/rotating platforms - I feel like you could get some inspiration from Chibi Robo for designing the levels in a home like this. It would also help if the coins were lined up in a way that would encourage players to chase them down and lead them around.
Game Mechanics Feedback - Sometimes the tongue sent you flying and other times it didn't really. Sometimes momentum sent you farther than expected but other times not as much. Had a lot of fun swinging around, but it was hard to latch onto enemies - maybe a targeting system like for Sonic - since I imagine that's the inspiration.
Otherwise the Sound and Art design definitely reinforced the cute, funky vibes.
I think that with refinement this could be a really fun game :)
