I'm having difficulties scrolling through the list of players ( both in a small window as well as fullscreen ) so my current review is limited to what I was able to use so far:
Making a simulator in a game jam is quite daunting and I think, considering the time you could spend, you guys did a great job so far!
I think all core elements are in and really like what I see so far. In the past I played a game called Speedball and this gave me the same vibe.
There were a small number of issues which limited me in really playing it. After initially registering ( personally, i think this should never be a thing for a jam, but that's a personal opinion ) i was unable to login in my second session, so I had to make a new account. Fullscreen does not actually scale up the window, so it's -very- small.
I hope to get a trick for the scrolling, since I really want (NEED!) the full experience :-D
