Mild spoilers below:
It's an incredibly nice game, and I love it to bits, buuuuut, there were some little bugs that I thought were silly and wanted to share
So, here they are, in no particular order:
First, the sliding on snow softlock!
You can get softlocked really easily if there's an abomination near some ice. If you slide off the ice into the abomination, you'll crash into it. This also gives you temporary invincibility. Trying to slide further will cause you to softlock, stuck standing above it all for the rest of eternity
Second, crash storage
A bit nitpicky, but when you crash into the wall, little things on the side of the screen show up. You can actually keep these around by getting a game over or switching screens while you crash. Interesting, but doesn't do anything much, and disappears as soon as you crash again. I do bring it up though because it's a forced encounter of the bug when leaving the ice rink.
Third, the water ghost
If you go under the water, you'll have a couple seconds where the polar bear leaves a hole and goes under the water. During this, walking onto land again is possible, and even lets you speedrun grabbing this riceball

This is also the only way (that I know of) to die underwater!
Fourth, the idle slide
If, when crashing after a slide, you quickly move another direction, you'll slide while idling, simple as that.

Fifth, snowball scam
If you talk to a snowman when you have 1 snowball, they'll say you've recieved 2 snowballs, but your total will say 2 snowballs instead of 3! The snowmen think they can get away with scamming me of my snowballs... (I'm mostly sure this is unintentional, since snowmen have dialogue if you already had 2 snowballs)
Sixth, Ice hitboxes
The abominations walk through ice most of the time

But then this guy politely waits for you to move it?! Unplayable
Seventh AND eighth, Walking on ice and broken buttons
Yeah, this just kinda happens here
Ninth, Repeating win noise
Just push an ice block towards a wall after completing a puzzle, fun sound
Tenth, push to win mechanics
Apparently, on the room before you finally escape the snow, the game just forgets to reset the buttons states when you reset the room, letting you complete the puzzle, reset room, then push a block to instantly unlock the gates.
Oh, and a bonus eleventh one, turns out winning the game doesn't reset gates, so you can just run through the game ignoring all puzzles after winning once. You can fix this by gaming over tho, so be careful
anyways, here's some silly graphics stuff to end it off.
a bed hat!
a see-through tree!
A weird looking corner
Alright, thanks for reading, and byeeee!
