Howdy,
Recently, my nes run of the demo version was rejected with the statement that this os reserved for the full version. Unfortunately, there is no indication that there ever will be a full version. I know of at least one other person who has completed demo version runs and several others who would likely follow suit. The demo is fun, has 3 stages, and is lengthy enough to attract homebrew runners. Id be glad to mod the nes demo version. I think it will bring some energy to this board. Otherwise, i see the board standing as a single run on a single platform. Glad to be involved. Thanks for your time!
I also thought that the NES version for this game was abandoned because I could only see SNES and Genesis updates on Kickstarter (the NES updates are just buried/old) and I didn't notice that a digital version was available on the dev's personal/custom web store.
Anyway, the version available here is the full game on NES so far as I can tell: https://www.second-dimension.com/store/eyra-the-crow-maiden
