2022 Update: I get asked how I made this along with steamed hams 2k3, quite a bit. It took me awhile to realize that not a lot of peeps look at the gamepage on rmn? So I added a link to the tutorial. in the description.
I made "Steamed Hams but it's rpgmaker2003" the exact the same way as this game, the only difference being that. I used Final Cut Pro 7 to create the clips and then QuickTime 7 to cut them up into animation sheets, which made the process a whole lot faster.
I'm working on more stuff, it's just post pandemic life has been really shitty.
