Ha, the world definitely needs to know the superiority of pineapple on pizza! I really liked playing this one, it really felt like you put effort into it. The levels were nicely laid out, and options for multiple routes is always a bonus. The graphics are simple, but using the unifying concept of pizza toppings helps them feel consistent.
There's definitely a couple of areas for improvement. You've already clocked things like additional animations and sfx, as well as the slightly buggy bounce pads (perhaps introduce a speed limit to the character controller). I'd also point out that there are a few points in the game where you have to make a blind drop, and there's no way to know if your going to land on an enemy. Perhaps have the camera move down or zoom out in these kind of areas? That shouldn't be too difficult with cinemachine. I'd also suggest against using coins for health, as it kind of goes against the visual language of a coin as an optional collectable. You can still have health packs double as score, I'd just suggest making them into pineapple chunks or something that a player will have less assigned meaning towards.
The player movement is fine, but there's a couple of things that can be done to improve it's feel. I'd slightly increase the movement speed and tweak the acceleration to give it more of a ramp up (not too much though or it will feel slippery). As for the jump you normally want the player to fall quicker than they rise (this violates the laws of physics but tends to be what people expect from platformers). You also generally want the users jump height to be proportional to how long they hold the button, it gives the feeling of more control. There's a great yt video called "better jumping in unity with 4 lines of code" that addresses this.
Sorry for the long post, just thought I'd offer a few thoughts if you were looking for points to improve for future updates/other games. This game had a lot of charm and I really enjoyed it. I hope to see more of your games in the future! Well done :).
