I'm planning on it, but I'm not sure just what to give out to patreons if I did... So it's in the cards, but maybe still need some more planning.
Here are some suggestions just because I've been patreon to some- gallery with vn, polls on what character to work on first, sneak peeks at CGs which will be included in the game. This is personal opinion, but you'll want to avoid offering rewards which are time consuming- knew someone offering to type up side-stories as a benefit but it was a turn off because that meant they were working on something other than the VN project.
