the whole game design (every mechanic, level and balance number), the architecture and the tech stack, the direction and review of every model, sound, text and screen, and the playtesting and tuning
nothing is bought: the bases are free CC0 packs, the jam's own packs and free sound libraries, all named in the list
I kept that list long on purpose so nobody has to guess
by the way, yours is the first comment I’ve received on itch
I’m extremely grateful that you took an interest in my game
