I feel your pain as atm i'm working on a open world Visual novel and you can tell by that alone that it's going to be a lot of work and im always having 101 ideas to add to it but not really having the time to think how could this effect the story etc
anyways i'm always ready for anything and to tell you if lets say you give me something you really like (e.g. fave band or movie) and gove me an genre ill come up with an concept idea for a game in about half and hour
but anyway again nice work with this one of the couple visual novel fur games i come across that i really enjoy so keep up the good work as to be honist i wish i could have the art skill you got XD it's the only thing that lets me down i draw like im 10 (and before you say anything though my dream job is a game designer I want to be more of the ideas man behind it all creating the story characters backstory etc)
...i just noticed how much i'm talking about myself here XD ill stop now good luck and just know that i support you on this (emotionally i'm too poor to give you money sorry ;_;) so all you can do is your best so go for it and never stop
