Is this on steam and if not are you planning on trying to get it to be available on steam?
I haven't given much thought about trying to get it up on Steam. Do you think it'd be important?
I think if this is a game you really want to keep developing you should but you will need to have a large fan base. So yes if you want to continue developing this for a long time. but in a way I think you will need to work up to it.
P.s I think this game is a lot of fun and has a lot of potential.
