As part of the Metroidvania fusion festival, Star Rift Saga will be discounted until November 10th. You can pick up the game for 20% off and the soundtrack for 10% off.
You can also save a little more with the game's bundle options. If you buy the game and soundtrack together, you can save another 20% on top of that, or you can purchase one of the other bundles that include other indie games from the Portland, Oregon area.
