What is the good life?
Part of your problem is likely that to playtest the game testers have to buy it at a retail cost.
From my experience on this site test versions are typically shared as PDFs for PnP free of charge. Testers get an in-development version (sometimes hosted where the developer can take down the share, sometimes in B&W / reduced visuals) and the developer gets playtest feedback to continue to develop their product. Even in other markets pre-production testers are not charged, they are potentially paid for their time and feedback (not really here but by larger developers typically of other products).
Actually, the PnP pdf and rulebook are both free on that gamecrafter site. I don't have the ability to playtest it right now, but it can be done without purchasing the game.
