Is this the full version of game?

nope!

if you look at the top bar, you can see the disclaimer saying that this is Early Access version 0.3.3 (the zero means “not full version yet”)

All data except username and account id will be wiped, premium shop purchases will be refunded as credit to your account, and redeemed codes will be re-usable once Lorwolf officially launches.
