Hi there! I don't know if this is still being worked on actively, however I discovered a bug a while ago while playing. In the scene in chapter two where francis is talking to you about your date with Deka, when the option to say either it was or wasn't a date comes up, both of the options lead to a bug screen. I decided to investigate this on my own and I believe I found the problem!
It said ""plot/ch2/ch2_03_frances_doubt.rpyc", line 116, in script" had an issue defining name "d". It seems that in the file "characters.rpyc" you defined a lot of charaters, such as nikolai, as a letter like "n" however it seems like Deka was left out of that list, meaning there wasn't a line defining Deka as "d". I could be completely wrong with this, as I don't actually make games and I was using an online tool to view the files, but it was just something I wanted to check out.
