IndieGameStand is now featuring Really Big Sky in a name-your-own-price deal starting at $0.25.
For 25 cents you get a DRM-free installer download. At $1 you also get a Steam key. If you Beat The Average (currently $1.59), you also get "The Lunar Pack" (two older games from the same publisher). At $10 you get not only this game, but also the previous offer (The Geneforge Saga) and the next one (currently unknown, will release on 10/16).
Really Big Sky is a super-fast, twin analog shooter for Windows featuring 12 game modes and full Xbox 360 controller support.
The Lunar Pack is comprised of two previous games from the same developer, Lunnye Devitsy and Wake. It also includes the original soundtracks from the games.
10% of all proceeds from this sale will be donated to Amnesty International UK.
