Slime Forest Adventure
Through PayPal, you can pay with most major credit cards (including Visa, Mastercard, and American Express), with MoneyPak cards bought with cash from places like Walmart or 7-11, or directly from your bank balance, from almost anywhere in the world. You don't need to set up a PayPal account to pay with a credit card, and you don't need a credit card to set up a PayPal account.
If you don't already have a PayPal account, and don't intend to simply pay by credit card, I recommend going first to the PayPal website and setting up your PayPal account before creating a Project LRNJ account.
This is a one-time payment for permanent access including all future releases.
There is no free registration level. Registration is not required to download the free version, which you can download from the front page.
If you pick a username and password, but don't complete the registration process (by logging in and making payment), the username will be freed up after an hour or two.
All old registrations are still valid, and some have been upgraded to reflect changes in the registration system. You can claim or recover control of your old registration on the member page, or if that doesn't work, I have full records of all transactions and if you contact me by email I can fix it manually.
