-32768 and 1 are both perfectly representable in the 16.16 fixed format, as 0x8000.0000 and 0x0001.0000. As far as I can see, this division should be perfect with no floating point shenanigans.
However, 0x8000.0000/0x0001.0000==0x8000.0001
which is throwing a wrench into some code I'm writing.
Other nearby operations work fine, such as
0x8000/2
and
0x7fff.ffff/1
and
0x8000.0001/1
Then there's another group of operations that seem to be technically misbehaving but in a possibly desirable way.
0x4000/0x0.8 0x2000/0x0.4 ... 0x1/0x0.0001
should technically all overflow to 0x8000 (-32768) but they actually evaluate to 0x7fff.ffff which renders as 32768 because it's higher than 32767.9999. Maybe this is intentional, and maybe it's helpful, but I mention it here because it might also be related.
PS: there are markdown rendering bugs affecting this post which is why it's weirdly formatted

HUGE credit goes to Krystian Majewski (https://twitter.com/krystman?s=20) at the Lazy Devs youtube channel for making this AWESOME tutorial series for Pico-8 roguelikes and RPGs (https://www.youtube.com/playlist?list=PLea8cjCua_P3LL7J1Q9b6PJua0A-96uUS).
Thanks to these videos I was able to crank out this pokemon-inspired, very dumbed-down, version of his Pico-8 roguelike game in under a week.
That being said, shockingly, I'm most proud of the main soundtrack theme.

A work in progress for a mod of Hungry Harry 3D featuring a feminine Harry called Mary
Story
The mushroom gang striked again, so Harry got at the shroom lord's castle, but he got kidnapped.
So now Mary has to go save him. Think of it as a sequel to the original hungry Harry 3D.
The story is narrated at the start of every level btw
I won't release any versions until it is completely different to the original

Lunar Mission!
I followed Dylan Bennet's Lunar Lander tutorial from the Pico-8 gamedev zine and kept plussing it.
After launch, try to land the craft on the pad before your fuel runs out.
Enjoy! :)
Edit v1.1: Fixed the palette swap so that it no longer triggers a psychedelic experience. Increased the required speed threshold to land on the pad by just a bit.

A physics-based puzzle game with fifteen levels.
Guide the ball around obstacles, to the target.
On the title screen, use the arrow buttons to select a level and O or X button to start play. You can quit a level and return to the level select screen from the pause menu. Gameplay is explained by in-game instructions.
Scoring is like golf: the fewer shots required to hit the target the better. Best scores and times are persisted.
Levels can be played in any order. However, earlier levels introduce game elements used by later levels.
If you're interested in designing levels, let me know in the comments and I'll write up how to activate and use the level design mode.

Theseus and the Minotaur
Theseus is trapped within the mythical Labyrinth, forced to contend with the ferocious Minotaur. The Minotaur is faster than Theseus, but has severely limited intelligence. Thus, for every square Theseus moves, the Minotaur will have the opportunity to move twice. However, the Minotaur's movement capabilities are limited to the following:
-If the Minotaur can move horizontally towards Theseus, he will do so.
-Otherwise, if the Minotaur can move vertically towards Theseus, he will do so.
-Finally, if the Minotaur can do neither, he will pass his turn.
In an open field, the Minotaur would outrun Theseus and eat him every time. However, the maze-like structure of the Labyrinth, coupled with the Minotaur's inefficient and predictable movement pattern, allows Theseus to trap the Minotaur behind walls and make his way safely to the exit.

You are melvin, a little guy with a big umbrella.
Melvin loves the night sky, but he noticed that some stars are out of place. Try to collect all the stars before the sun come up-- but watch out for the monsters!
Use the arrow keys to jump and move left/ right, and try to collect all the yellow stars. Game ends when you reach the sky (about a minute), collect all 100 coins, fall off the platforms, or lose all lives (the monster's body is safe to touch, but getting hit by a bullet will cost a life).
If you get stuck, try going off the side of the screen! If you jump off one side, you'll appear on the other.
