Today, I have decided to release the sandbox mode as a demo in preparation for the game's main release. I'm still unsure on an exact date (and it would be no fun for me if I put myself on that rigid of a plan); however, barring the space time continuum distorting, I will likely be releasing the main game next year, likely during the Summer.
In addition to the sandbox update I have also finished my new menu system for the game. This menu features an in-game interface which can be used to quickly choose between blocks. This will eliminate the need for the player to switch between rooms.
Also, contained within this update are a few blocks that appear duplicate. This is actually how blocks you have not yet encountered will appear within the menu. I chose not to include these blocks at the moment as I wish to keep their properties hidden until later on.
I hope you enjoy this little taste of what's to come.
