If we test out the platform and drop our constructive feedbacks, will it not make us ineligible to join the review campaign when it begins?
No, this should not make you ineligible as you can make a new account to join the review campaign afterwards

Do you really accept every countries except Costa Rica? this is really rare because most countries didn't want to accept players from US and it's territories, EU and sanctioned countries by US.
Yes, we allow any player form around the world to play on our platform freely, we're libertarians at heart and so we're VPN friendly and don't believe in KYC or restricting gameplay. The only country we are not allowed to accept is Costa Rica (due to the Costa Rica framework we operate under).
Employing a rep to answer questions is a plus. Just in case, though. Can we get a confirmation from OP that @PrecariousPanda is part of the team?
Yes will get this done to avoid confusion, thank you for the suggestion
