If you received a playtest invitation, it’s because your profile matched certain criteria for the project. Please consider accepting, as any feedback is invaluable to the developers. If you believe it was a mistake, you can review your profile to make sure it matches your interests.
Having said that, participation is voluntary. You are free to accept or reject any project assigned to you!
Please note: if you fail to respond to some consecutive playtest invitations, your account may be marked as inactive, and you might stop receiving notifications for new projects over a period of time.
