Hello Celtic.Brewer,
This is not a ranked jam, and there is no peer-review system in place.
With that said, many creators would be happy to trade download keys of their games if you ask them. (It is a bit inconvenient that itch.io has no direct messaging system.)
If you just want to see an example of a Guided by the Sun game, I have restocked community copies for The Sol Survivor.
Best regards,
Arthur
P.S. IMHO, while playtesting is good, I find it overrated for narrative games. Unless you have a mechanically complex combat system, playtesting is not really needed. (It may be desired, but not required.)
