I would love it if I could put it on a cartridge, and I haven't yet looked at how that could actually be done, although I have seen some people release cartridge games (Brad Smith's Lizard and toggleSwitch's Project Blue come to mind)... But it has to at least run on an emulator, and on an NES via an Everdrive (basically a cartridge with an SD card in it, in which you can load NES ROMs).
That's what I'm aiming for, anyway. But it's going to take a while until we get to that point...
I may be shooting myself in the foot by making so many animation frames that may need to be discarded judging by how few frames characters in NES games usually have, but at least that's good for practice. It's been a loooong while since I've done anything similar to that, and when it works it's really satisfying.
For the BAPT (

abdominal armor? I don't know) I'm thinking I *could* alternatively do like a Mega Man thing and overlap the main sprite with another 8x8px one (well, actually more than just a single one if we account for animations) with 3 more colors, but that has its drawbacks. I'll have to use those 3 extra colors somewhere else at all times (which isn't necessarily a bad thing...), and that would count towards the 8 8x8 sprite per scanline limit, which like I said before I'm trying to avoid... But it's really tempting!

I'm having a bit of trouble drawing the jumping frames straight into pixel art, thus why I'm resorting to sketching them on the side...
Thanks for the feedback, cels!
