Hi! We are working hard on our upcoming game, Plith. We have showed some screenshots in the past, then we have collected several suggestions and have changed some things relying on them. Mainly, we have changed several parts of the HUD. Moreover, bugfixing is a constant during the development. :)
The (development) demo is available for Windows, OSX and Linux. It is a development demo since we are still working on it, so it is not definitive yet. :) Please, let us know if you face problems! You can find the (development) demo here.
The game is in an advanced phase of development, please track it if you are interested in it! :)
