Hi Kritzlof! So glad you're interested in this jam. This year, we are only awarding prizes for students enrolled in US schools. We hope to expand internationally in the future. So if you want to develop and submit a game to challenge yourself, please do, but you wouldn't be eligible for the prizes this year. I hope we can expand in the future!
One more thought: if you're interested, we're collecting some resources on environmental games on our Discord server (https://discord.gg/dWagWC3UKy) like the Environmental Games Playbook -- which you might enjoy if you haven't seen already: https://igda.org/resources-archive/environmental-game-design-playbook-presented-...
