If it's an intentional and safe site then all is fine. I'm completely unfamiliar with Totem so its all new to me. I just wanted to make sure :) Cause normally if you download a recent game uploaded on itchio, you don't 100% know if its safe or not, and having a game launch your browser unexpectedly after launching a .exe 'is normally red flags' kinda app behavior.
But again, if intentional and secure? No issues and hope the game goes well.
