There is a news about it on their Patreon, so the game is definitely in development. I think this is just the latest public version, so to speak, for introduction, and we should expect the rest in the release version.

The creator hasn't posted a dev log in over a year and the current build you can download here is from 2024. To add on, it's also VERY broken to the point that you can soft lock yourself very easily.
I can understand uploading versions earlier to Patreon than Itch, but this delay is ridiculous. Maybe stop charging 5 USD for it if this is going to be the case?
