Little hints please? List of things I don't know yet after 14 hours (spoilers)

[Drillbert]

I don't want spoilers (I think).
The game is a little frustrating, but I'm making rewarding, if slow progress.
This is what I've managed on my own.

4 bunnies
58 eggs
I've seen the credits


Items:
Bubble wand - upgraded
Room for 6 firecrackers
Frisbee
Yoyo
Slinky
Remote
Lantern
UV lantern
Wheel
Flute
Spinning top

I have opened 8 animal mouths.
I know 2 warping tunes: one to reach the animal mouth room and one to reach the opening to the big well (to the right of the firework room).

Here are some things I don't know and things I've tried.

I can still access the M disk and summon the ghost cat, even after getting all 4 flames.

There are pedestals with symbols matching my map stamps. I've tried dying in a room with a skull and flute-teleporting from a room with a swirl. They have a number of dots under the symbol, similar to the little yellow lights that turn on at doors, suggesting some require more input than others.

On the climb back up after getting the UV lantern, some jellyfish show directions on what looks like a D-pad. These directions when played on the flute do nothing.

For some reason, pressing up 4 times turns me into the guy from Fez.

There's a room full of skulls near the firework room with a chest I can't reach.

There's a room in the top left of the map that I don't know how to solve. I can move on the spikes with my wheel, but can't jump high enough to climb the room.

I used firecrackers to send a bat away, but I don't think he left me anything. In the room to his left stands a medal holder, though I don't yet have a medal to put there.

I found an incubator. Perhaps it does something after I get enough eggs.

Some rooms can have an angry kangaroo spawn in them. They are marked in UV on the walls, but I don't yet know the conditions causing the spawn, nor what I can do with the kangaroo.

The cuckoo clock at the bottom of the map activates on the hour, every hour. I don't think I can do anything with the cuckoo. The UV light shows the numbers 90, 300 and 30, written on the doors. The numbers above the doors have never gone above 000.

The door above the TV room is locked.

There is a strange doughnut shape to the right of the clock room.

The egg room when viewed in UV, show horizontal bands across all the eggs. The same horizontal bands can be seen in the room you find the flute in, although only 1 band per note rather than up to 3.

That's about it! I'm mostly just letting you know that I've done my due diligence before asking for help. I'd be very grateful for just one crumb of a hint.

Mess with Kangaroo.

Obtain egg.

Also, look at jellys again.

The kangaroo seems friendly enough, until I throw the frisbee at him. He made a heart when I played the flute, or maybe he was about to do that anyway. It's easy to know where he spawns, but hard to get him to go there.
Silly me for writing down the jellyfish wrong. But it's kinda useless? It's only one room different from a warp I already know.
Got another bunny, it's the duck one!

I'm currently trying to deliver the M disk to the circular recess to the far west of the shrine. It's pretty hard.

[Drillbert]

Well it was worth a try I suppose

I wasted a bunch of time trying to do that too. For now I'd recommend focusing on the kangaroo, and keep seeing how it reacts to different items

[Drillbert]

Ok! Kangaroos down, bouncy ball obtained.
Now I'm up to 60 eggs.
But that damn top left room is still giving me headaches. I was hoping that the ball would bounce me through the spikes but it doesn't seem to react with other items at all. It doesn't react with the skulls in the room with two chests either.
I tried throwing the ball at the monkeys, since they were throwing stuff at me, but no luck. I remember seeing breakout blocks somewhere else in the map, so I guess I'll try to find that again.
Found a couple more bunnies too.

The top left room requires a hidden movement tech, kind of like the bubble jumping one but quite a bit harder to pull off consistently - or discover by accident. The room itself was kind of like a hint to me though. Not a whole lot of options + one obvious answer that just barely doesn't work = is there a way to abuse this so it does work?

[Drillbert]

My guess would be to spam bubbles so that you don't have to jump. Just walk off onto the next one.
Either that or use the bouncy ball to clear the vines so you can use the frisbee.
In other news, I've got 64 (well 65) eggs! I looked up a map with the eggs, but did all the puzzles on my own.

Maybe you have to use a different item? One that lets you travel left and right in a straight line? (It's hard to pull off though, gl)

For the egg room, go to the left where the 3 chinchilla's are, the UV light should show you something in that room.

For the pedestals. Think of your ENTIRE map as a "connect the dots"

Skull room - each skull is a time you died.

Incubator - maybe you need a special egg

Doughnut and TV locked door are not accessible based on how you have described your progress.
