Respectively

Ok, this game no longer needs any beta testers, so thanks for the help, and I’m done.

Try: if.game-testing.org/

Or ask users here to post or private message you their email addresses, then send them your game along with info about what you’re trying to achieve with the game and what kind of feedback you’re looking for.

Thanks for the help. I edited my post and put it on if.game-testing. Thanks again!
