this game looks good, but please for the love of god reconsider not using renpy. i know it feels great to make your own vn engine but the lack of options for text speed, window size, saves etc. make the experience slightly worse (i read faster than the text, and sometimes i click space twice out of habit and i can't even rollback to see the last line. not your fault really, but still annoying). not to mention that you'd get cross platform easily (this game runs like ass on macos & linux using wine, and doesn't work with proton because unity game) and it makes development infinitely easier.
either that or someone rips the assets and ports the game to renpy by themselves, like what happened with that rick and morty game.
game looks great otherwise and i love the artwork. excited for the final release
