Every time I open the game it crashes. Other version demos work. The last tine I opened the game, it crashed as soon as I chose which save to play. The game doesn't provide an error message, but since I have a MacBook, I get a problem report.
I'm guessing this is your steam profile? https://steamcommunity.com/profiles/76561198849074049 (I noticed you posted on steam too). Make your games public so I can confirm you own Aground on Steam (edit profile, my privacy settings, and set my profile and game details to public), and I'll give you an itch.io copy of the full version. Once I confirm you own the game, you can change your privacy settings back if you'd like.
