It's no mystery HLM is one the most hyped indies of the year, from a strictly monetary point of view it was worth at least half the price of admission. Pid is also new and worth a sizeable chunk of it ATM.
And just FTR:
Offspring Fling, Home and VVVVVV are currently available on Steam cheap as dirt. Jottobots is 1$ on the Humble Store.
Swift*Stitch has been PWYW from the author and featured in an IndieRoyale.
Home, VVVVVV, Cortex Command all have been in some HIB, some of them twice.
On Steam: 30 flights of loving is cheapish (although very short) and Puzzlebots cheap.
Deepak is free (ad-supported online version)
BTW the weather's forecast for this weekend is bundle-y with a chance of Indiegala XI.
