If you paid 10$ for it seek support if you paid less you bought 0.10 and it only says 0.15a cuz of game title.
I re-bought 0.15a for 10$ few hours ago and got no issue.
I paid $5 + VAT (-50%)
Then it's not enough. To get access to 0.15 you need to pay 10$ (-50%) cuz 0.15 is costed at 20$ before discount.You dont need to pay more to get acces you will just get it in a 1-2 weeks after release FEYADA explained it in post below.
I got it. Paid some more. Shame that old saves dont work or did I miss something?
Well I lost my saves too.
