Signing up as a free Visitor gives you access to the comment threads and any other restricted content. It’s great to have your interest and I hope you’ll consider joining as a full member once you’ve had a look around.
The other tiers cost a small amount of money to help support my work, but in return you’ll be able to download new development builds of the game as they come out, and look after your very own creatures.
Something I always want to know before signing up for anything, is whether I can cancel online. Yes, you can! No questions asked. You can also upgrade and downgrade at any time. If you downgrade to the free tier, your creatures will be put into suspended animation until you resume as a full member.
