I can understand the difficulty but it's been a year without even a 'barebone' update, the dev should at least add a small, if uneventful, update just to show people on here that the game is still being cared for.
you do whatever you want. my answer is you either wait for an update that is stable here or experimental update on patreon. also now theres an update here. the thing is since here its a fixed price, dev want to update here when its a "stable" update while on patreon it starts at 1$ a month but you get access to experimental build and more hand on approach with the dev. i think its fair since you end up paying more on the long run on patreon to have more updates while here you paid fixed and experience stable builds. at the end when the game is finished you will have the full game no matter what
