Good luck to you! Definitely a good idea to start small (and expand later if you have time), especially if it's your first VN! ^ ㅡ^ It sounds like you've got a great plan ahead~! Looking forward to playing yours. :3
As for my first day. . . I've been busy moving (moved out Feb. 28, moved in March 1 at 3am ㅠ ㅡㅠ;;) haha... I still don't have internet or gas yet! A bit hectic so far >ㅡ < but hopefully I can start to work on things really soon!
