i also want more of this game too honestly. i wanna try keep adding stuff to it post-jam, i got a couple things planned for it in fact..
for paying money for it, dont. i dont think lawyers would be too happy about me profiting off a game with a bunch of copyrighted assets. i think the most i could do to allow people to give me money is a donation link or something (or just give me money through the scarlet system demo, since you can name your price on it)
as for the duration of the game, yea thats valid lol, it can take a while to beat the game first time around. the quickest ive seen someone beat the game was me, i recently speedran through it and it took me 8-10 minutes to do so
anyways, im glad you liked my entry <3
