There are four things that I think should be mentioned in regards to the camera, jumping under small ledges, the rolling, and the Pagie. Since the last one has been mentioned multiple times as I have noticed people already address it in the animations thread, you don't need to read it if you have read it elsewhere.
Camera: The camera is my biggest issue. I understand how weird it is to have the camera clip into objects, but preventing camera movement doesn't fix the problem. I would rather the camera zoom really close to the characters face rather than not let me see around me. In the toybox, you can't move the camera past things like walls, pillars, little bits of terrain, etc... without either having to move awkwardly or rotating the camera completely around, which might end up being impossible if there is another bit of terrain poking out of the level ground. I wouldn't mind if it decided to roll around a wall or pillar straight over top of the characters, but it just won't let the camera go past a certain point. If you want to look around down below or something, but where you are looking has pillars on either side, you will be unable to look around without trying to manipulate the camera by moving close to certain pillars in order for the camera to rotate around it. Sometimes, you can't do this either, so it became a little bit frustrating. Also, when you go behind a chest backed up against a wall, like the one at the top of two small slopes, the camera will just continue spinning around or force itself to be on the opposite side of a wall preventing visibility. If camera movement does have to be limited, perhaps chests should be excluded.
Another point about the camera, though I know I am in the minority, is an invert X option. I don't know how or why, but I got really used to playing various games with an inverted X if it is a third person game, even playing games like Dark Souls with inverted X, so it would just be nice to have the option. It is fine if it is not put in, but I just thought it should be noted.
Spring Jump Under Small Ledges: Though it can be cancelled out of with any other move input, it is possible to get stuck in a falling animation. When doing the spring jump thing under a small ledge, or behind a chest back up against a wall, twice in a row, they will end up stuck in the falling animation. Movement is still possible and this is really minor since it can be cancelled out of very easily, but I thought is should be mentioned.
Edit: Doing the spring jump once while leaning into the back of an opened chest does this consistently. I tried to recording it so you would get an idea of what I mean. www.youtube.com/watch?v=VurLS5QRtVs
Rolling: I already mentioned this in the animations thread, but it should be noted why it is a problem. From looking, it seems that there is a full cycle of animations for the roll, but it looks strange to have that cycle just stop on a particular frame when idle. They just sort of look frozen like statues and no longer feel alive with Laylee just standing there, mouth agape, not moving and Yooka with eyes perpetually staring into the void. I really like the animations for the roll when moving, but since the roll is a good way to traverse the area, I sometimes just stop to look around while still in the roll and it ends up looking a little strange, as if the game froze, but not really.
Pagie: It has already been stated by others, but there needs to be an animation when you get it. Maybe Laylee reaching for it and Yooka pulling Laylee back and putting the Pagie away by eating it or curling it in his/her tail or something.
