Is it a mobile game?

Yes and no. Undervault has been targeted for both platforms. I released a PC version in September 2017 on itch.io. Android version was released on Google Play later, in November 2017.

What is the current state of the game?

In development. Preparing for Steam release.

What do I get for my purchase?

Access to the full game and all upcoming updates. If you bought a PC version you will also get a Steam key after the game is released on Steam.

Localization?

Planned. If you want to help translate the game to your language please contact me.
