Alex and Hayes have been working hard to add new content to SOL, but it's not an easy process. Each sprite that is made has to be incorporated into the game in a unique way. After all that is done, we have to fix, balance and test the content before giving it to you.
Once the basics are done and it gets working, I need to create sound and music for it. We've taken a while releasing new content since we're preparing for a launch of the demo, but to bid you over, here's a nearly complete menu with sound and music.
We're still accepting all your input so feel free to send any feedback in and we'll take it to heart. Thanks guys!
