I want know if buying Voxatron gives me access to the full version of Pico-8. I'm not sure if the wording is saying I'll have Pico-8 until it gets out of Alpha or if I buy Voxatron while it's in Alpha, I'll also get Pico-8. Thanks.

Yes, if you buy or bought Voxatron while it is in alpha, you get a regular copy of PICO-8 that comes with all future updates.

Thank you.
