Nope, should be a free download, listed as 0.6.2. Any chance you bought it under a different account?
Viewing post in First content pack for GutterTrash now out on Itch! comments
Hmmm dont think so ? I used to have another account but it was hacked quite some time ago so itch services striked it down and gaves me back my purchases on this account. It happened a few months ago allready so I doubt it is the reason as Guttertrash is still recent...
(Never mind it was more or less the reason why. My account now have two emails linked to it and one of them just overights the other; so if I want to redeem something I paid for with the other email I need to ask for the links to be sent there)
Mistery solved !
