I got those bugs too! In Andrew's route, I also got some dialogue in French when I was playing in English. I went digging through the files to see the CGs and I'm so glad I did, they're beautiful!
I am really sorry and the bug has been identified. I have updated the game and it's now available. Could you tell me if you make it to Andrew’s CG, please ?
There is no save option since it is a small game but don’t worry, it is planned for Choosen 2 ;)
