Hullo! As of now, store is now visible and demo is available for download. Feel free to leave your thoughts on the demo and how to improve the gameplay in the Steam's discussion forums.
Release date shown on Store is mid-October, however this may change depending on development. In any case, the game is intended to be released before December.
About localization, if you are interested in any language in particular, feel free to also leave a message in the game's forums (they will be implemented progressively after full release).
