The last game, Really Big Sky, didn't seem worth mentioning, and it didn't sell too well.
The current game is Brainpipe: A Plunge to Unhumanity. It includes a Steam key if you pay at least a dollar and a bonus game, Blobís Organism, plus several game soundtracks if you beat the average.
If you got the May Hurray bundle when it was available you already own both games, so I doubt this one will sell all that much. Since I didn't I'm a bit curious about it. Anyone know if it's worth getting?
