Thank you for the reply!
Came here from the man alone video about mausritter, and he actualy spoke about this same issue.
You have to pay the full 5$ to unlock the adventures, it doesnt let you pay the 2$ extra.
If it where possible to upgrade, I belive that would be the best way, if itch lets you.
I have no clue how to improve it besides that. I knew about the issue, so it's on me.
thank you
