Old stuff still on the list:
Landing from a jump cancels the attack, which is not so cool.
Switching maps repositions the game's window.
If you make the game full screen, then go back to windowed, the game is always the top window.
Holding left at the start after the storybook intro makes the character face the wrong direction during the intro with pop up textboxes.
(3. Talk to Sahasrahla (in the house). As his "sale menu" is opening, hammer up. Close the sale menu. A blank text box appears on the screen.) This is not fixed. Image:

(2. Apparently, doing the above with Sahasrahla in the cave entirely disables the menu. I can't even read signs. Running into the boss fight with the menu disabled brings up a blank text box, then restores the menu.) Still not fixed. I can make a video if needed to help reproduce, but activating it is no different to the above.
In addition, it seems you can hammer up while the sale menu is closing as well. So to be clear, it does this whether you do it while the menu is closing or opening.
(4. Hold left+right. Swing sword. Enter glitch stand state. In this state, you cannot move left or right or use the sword. You can only jump (holding the standing frame.) Landing fixes it.) Partially fixed. Hold left+right+down and swing sword for more strange animation. I might be overstepping "just tester" etiquette here, but the way I fixed things like this is, "if left+right is pressed, neither left nor right is pressed. if up+down is pressed, neither up nor down is pressed." (You can even be trickier, and when right+left is pressed, you accept whichever one was LAST pressed.) Right now it seems like additional cases are being created. Like if you press left+right on the ground, it's like neither direction is being held because you stay facing either right or left. But if you jump, you always end up facing left. This always facing left while jumping isn't a problem, just gives insight into how things might be being solved. Apologies if I'm overstepping or just plain wrong about it.
(9. Same spot where you could previously run, crouch/stop crouch. Instead, run, crouch, run, crouch, press left/right, then E. You can then press start to open the menu (which cancels the glitched stand state), run to get further in the wall, and be outside the map.) Still doable. Just run, crouch, stand. Image:

Some other places this can happen (marked in red where I started from)

Moving Platforms still don't always spawn.
New Stuff:
A green column with an E at the top now appears where cutscene triggers are. Probably just for testing, but eh. I'll throw it out there anyway.
It seems there's a way for your save file to get deleted. Not sure if it's because I selected new game and quit during the intro or something else. I'll try to get repro steps at another point, I'm out of time now.
Things I did not retest (deleted file!):
You can't double jump after walking off a platform.
Taking away control from the player after using the magic to activate bridge thing is not good. If you jump forward and shoot it, you'll die while it's coming out. (I was trying to beat it without ever getting the magic to change things up a bit, so I didn't test this)
It seems you're dealt "airborne damage" when standing on moving platforms. This is bad because bats!
Everything not listed at all in this post is either fixed, or I figured it's not that important right now or by design. (Like menus needing start to go back and bats perching in air.)
