Roundabout 3 is coming to Steam on July 13th! Both the game and soundtrack will be available for roughly $1.99 (or the equivalent in your country's currency) each, or 25% off when bundled together. The game features Steam leader boards, achievements, and has 6 different levels each with their own unique music. Check the Steam store page for the full details, system requirements, and to add it to your wish-list if you're so inclined.
In other news, my two other Steam games are currently 50% off in the steam summer sale (until July 9th, 10AM Pacific):
That's all for now... Thank you!
