While the rest of the options worked fine with only 2 choices, each 4 characters long, I think running will need more flexibility and I think it would make sense to have the following four choices:

• Press B to attack when standing or in the air, hold B while walking to run (current default)
• Press B at any time to attack, hold B to run
• Press B at any time to attack, double-tap d-pad to run
• Press B at any time to attack, hold B to run, double tap d-pad to run (new default?)

I'll have to come up with shorter names for these before I can have them as menu choices too.

I've been checking on your project for a while, it looks very promising, congrats!

One thing I've noticed is that while the default run method makes it impossible to shoot while moving, the alternative one (the double tap to run) makes it a bit uncomfortable/unconventional to run, specially when switching directions while running.

Why not do like in Super Mario Bros 3 where the B button will shoot even while moving while at the same time allows running while pressed?

It might cause you to shoot unintentionally sometimes, but I think that would be ok in most cases. You could still keep the double tap for running without shooting for the cases were you really need to be conservative with the attacks (but so far all the abilities I've seen can be spammed without worries, honestly).

Detect a PAL console and adjust the music, even if none of the actual speeds are adjusted. This should be easy because Pently is already built for this.

I want to do something similar to Mega Man X5's Duff McWhalen fight, but not sure past that. The fact that you can actually melt ice or also now explode it should make things very interesting.

I noticed in a lot of my secret/challenge areas I just have like, a health recovery items or lots of coins. I should probably actually have it so there's one secret per level that you can collect, that actually gets marked down somewhere.

You can get trapped between two screens, quickly cycling between them. Also the level exporter still doesn't handle this very well at all; enemies are in the wrong places, and it doesn't place barriers correctly. There's still that bug in level 2.

They should have a puzzle piece icon rather than a standard icon. Probably should also make it clear if you're entering a puzzle level, maybe by returning to the level select after completing a stage?

In my current plans, the story parts will be told with cartoony cutscenes with characters below a speech bubble or thought bubble or a narration or whatever (like this).

When you move the cursor past an empty menu option it should skip until you get to a non-empty menu option. Probably don't do this while you're rearranging an inventory, but do it otherwise?

I think it's just the metatile getting written to the map wrong, since pausing and unpausing fixes it. I think it also has to do with toggle switches.

The default for Pently is to make $4011 start at 64, but that affects the volume of the noise and triangle channels. I changed it to 0 to make the music sound as intended, but that means the voice samples now have a pop when playing because they abruptly change $4011 from 0 to/from 64. I changed it so that there's a ramp instead, but can it be better?

A lot of levels don't use palette 4 at all, or use it sparingly. I can use this for lots of things like actually blue water, or for a separate palette for background elements that contrast against the foreground.

At least in 1-5 I think it'd probably be doable to make the water actually blue. Maybe more of like a light cyan? So it doesn't interfere with the other stuff.

Since the songs are all the same length (64 rows), I think a pretty straightforward solution to this would be to keep track of how many rows the song has gone on for, and then pently_next_row that many times before finally doing the loop in pently_update to write the state to the channels. I think that might be what skip_to_row_top actually does when rehearsal mode is on.

Through some unknown means, an enemy can have its ID corrupted. This caused a crash for one playthrough of the game, and while there's a safeguard to despawn any out-of-range enemies, I would like to fix this.
