First of all I just wanna say I love your game especially the renders of each character idk how but you've made koikatsu look amazing! Honestly you've inspired me to try and look into the process of using koikatsu to see what else it's capable of so that one day I might make my own visual novel or just some animations for fun.
I've read that you just use koikatsu and Photoshop to make the renders but might I ask what version of koikatsu you've used? Cus googling I've found 3 version with one on steam and the normal version as well as one called sunshine?
Also if it's not too much to ask what program did you use to create the backgrounds? was it just blender or do they come with koikatsu itself?
Sorry for the wall of text and I'm honestly going to be following this game to completion not just for the awesome renders but because of how you've listened to your community and made improvements like the traveling between both maps, keep up the great work!
