Note: If you already have the full version, run Pixel Gravity and use the "Check for Updates..." option in the File menu to download the latest version.
The demo has most of the features of the full version, with some restrictions.
It cannot save simulations, it can only load the simulations it comes with, and only one of its simulations can be modified.
It will also close itself if used for more than 5 hours at a time.
The full version has no restrictions: it can save, load, and edit anything, runs indefinitely, and even includes a bunch of extra simulations. This version costs $10
(in U.S. dollars; other accepted currencies are fine).
- If you have an activation code, you've been paid for already (hooray!), so just head over here.
- If you buy 5 or more copies, the price of each one is reduced by 10¢ times the total quantity: 10 copies cost $9 each, 20 copies cost $8 each, and so on (minimum price is $5 each for 50+ copies). Contact me if you need an quantity other than the ones listed.
- If you don't have a PayPal account, make sure to give PayPal a valid email address when you pay, especially if you buy multiple copies. (You'll get all the activation codes in an email; it may take a few minutes to show up and/or land in your spam folder, but if it doesn't appear, contact me.)
