UPDATE: 7/15/2018
Some character sprites are started! I managed to finish a lot of Hikari's (the girl) facial expressions and poses, but there are still a few more I need to draw/paint. Omata has sadly only been sketched, but at least I've started lol! I've been working on graphics for a full 24 hours now so I think I will take a break and revisit my Twine draft. I'd like to see if I can start getting things in Ren'py soon...
