Just a quick update to say that development is coming along well and I just released a closed alpha build of version 0.12. You can read full notes on what I've been working on here: https://www.patreon.com/posts/ghost-grab-3000-27915759
I've recently implemented localisation, so the game will support several languages at launch. I've also made the first Steam test builds for Mac and Linux.
I hope to reach Beta in the next couple of weeks or so, and I'm now aiming for an August release on Steam (fingers crossed).
