As part of the recent Yacht Club Games Presents, the studio gave an update on Mine the Hollower, the short answer, its still in development. You can check out the video update below, just ignore the weird mad scientist setup.

As for when its coming, there is no date yet. In fact, the update didn’t really reveal anything of major interesting, here is the statement from the devs about it.

As this expansive new adventure continues to take shape, we are nearing the completion of the initial pass on all level content.

As the game has evolved, it has grown significantly larger than initially anticipated, incorporating an expansive overworld and more RPG elements. As we approach the next phases - balancing the gameplay, refining the script, and polishing every gory detail - the anticipation is palpable here at Yacht Club Games. We cannot wait to deliver a game teeming with fun and fear!

Now they are promising a full reveal and gameplay in the near future, but that scale depends on what they consider to be near. Either way development is ongoing and we just need to wait.

The projected platforms for release are Switch, PC, Xbox and PlayStation, but as the game is still in active development, that might change.
