Okay. Here is the culmination of a little more than a year's worth of effort. It's what I mentioned elsewhere under a Hebrew name.
The final screen count is 4744, making up 310 levels in this... level.
It took me about 2 and a half hours to finish playing it, it took a couple friends some indeterminate amount of days. My sister is clocked at over 10 hours right now.
This is primarily a puzzle game. If you've played the trash can BLOCKS game in Too Much Soda, it's kind of like that but way better in every way. If you haven't, play this anyway.
There is a story that goes along with it, very illegible, but a friend likes to call them "cutescenes" and I decided that's indeed what they are.
Anyway.

So don't freak out if Knytt Stories doesn't immediately respond when you start it, it's just loading. Yeah if anyone was wondering what happens when you have a big level, apparently that.
Oh, and there are four endings. One "bad end", one "good end", and two literal side-by-side other endings. If you get all of those, you probably found everything there is in the game, which is generally straightforward. Uh, in a sense anyway.
Edit: Oh 2, an important thing I forgot. Don't try to play this all in one sitting. Not only is it a long game, it also acts weird if you play it for too long. Specifically, the custom objects freak out and stop working.
If that does happen, or if you suddenly drop down in infinite nothingness (which I think is a byproduct of the aforementioned issue somehow?), turn off the game and then turn it on again. Yeah like what the guy says in the IT Crowd.
Edit 2:
I decided to make some very minor adjustments, and now here is a version that is slightly less difficult in like... six or seven spots, but more notably it's easier to see which blocks are deadly because their letters are tinted red.
