So I'm not sure how to buy the 29.99 model.
According to the picture, I bought a 45.
if u paid 29 bucks for it then thats for the FULL GAME the FULL GAME isnt released yet here is what dev said
in order to access beta its the 45 one- it says it too...yall bought the full game pre order which is 29, the 45 one is the BETA and the 60 is the BETA and full game so if u want to access beta u need to get the 45, in the update the dev said contact them to get a refund if u want to up the price for 45 since sadly itch io charges full price
