Yes. The free version will always be v0.30 but the early access will give keep giving you the newest updates.
so since I bought it I am sure to be always up to date even after 0.30 right ?
If you bought the $8.89 version yes.
so if I donated a lower amount of money I am basically cut out of newer future versions
$8.89 gives you all future updates plus the full game when it is released. The demo version will stay at V0.3
