Hi and thanks a lot for your comment !
The scrolling not working in full screen is definitely weird, in insight we should have added another way to browse your players without it. I'm going to upload a downloadable version to the itch page, hopefully it will make you able to play in fullscreen or, at least, get the full experience. Thanks a lot for reporting by the way.
I usually share your sentiment on registering in jam game but, at the time of making this, it seemed like our best option for a persistent multiplayer game. We probably could have managed something by using the player's itch account in retrospect.
Anyway thanks again for sticking by, this was definitely a huge challenge in such a short time.
