Definitely a very interesting concept. Unfortunately no one was on at the time; I suppose I can try again later with a friend. The mechanics were really nice, though I found it hilarious how the text behaves once 10 is reached XD (Perhaps you could dynamically add room for a second digit, or shrink the text to fit two digits?)
I think having some system in place for setting the target score or for easily resetting the score to 0 would have been nice. If a target score is added, I’d also add fireworks to the winning team’s goal XD
The graphics were nice, they’re decent given how strongly limited the time is. That said, I do wish the models were a bit more complex, and that some textures were used to spice up the textures, even if textures are only used sparingly to keep the minimalist art style.
Some things like allowing someone to choose team colour, and a scoreboard for how many goals a person made would have also added to the gameplay element.
Of course, music and sound effects were absent. That would probably be the first thing to address if you continue working on this after the jam (which I think you should tbh).
All that said, solid game! I think the foundation is brilliant, and that with some time to flesh out the rest of the game, you could have a really damn impressive game on your hands!
