Ever thought of opening a patreon? I don't normally comment but I found this game enjoyable and would probably be up for doing a monthly subscription there are probably others who would do the same just a thought. Cheers.
I thought about it, however, with a Patreon or Subscribestar, people normally expects some sort of reward for supporting, the platform is designed for that. I already did a Kickstarter with rewards, so doing another kinda feels overdoing it. If I open a Patreon or Subscribestar exclusively for the game, it will probably be one without rewards, aside from occasional updates or polls.
