These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: They Bleed Pixels
Scrappy Mechanic: The ice patches, which causes your character to slide to an almost ridiculous level.
Expanding on the ice patches, you literally cannot stand still on them. If you are on an ice patch, you're at the very least inching forward or backwards. In addition, the way you accelerate on them is non-intuitive. This is especially noticeable when you try to use your dash attack, where you may not move at all, or, on the other hand, you may fly into oblivion. Finally, they do not count as solid ground or walls. You can neither wall jump off ice patches or set up a checkpoint on them.
