For some reason, I'm thinking:
- Six Sided Sanctuary
- Sky Nations
I kinda doubt it, Sky Nations is for sale in Store...
BTW, I dont see any mention of Desura on SN page...
"Next Game Hint: It's for PC, Mac and Linux and on Steam"
So, variants now is:
Scoregasm (there is also desura, not mentioned in hint)
If we take hint STRICTLY its Proteus.
