One weekend. One game. One challenge. 🦊

To celebrate the public launch of Nimble Fox, we’re inviting the gamedev community to take on a 48-hour challenge. Use any engine and tools you want, team up or go solo, and see if you can turn an idea into a fully playable game before the clock runs out.

To end the event on a high note, we finish with an afterparty, a DJ, snacks and drinks, and an opportunity to network with peers and mentors. 

This is a hybrid jam, you can participate fully online, or join us in Helsinki at Founders House (capacity is limited). More info on how to get there will be shared on our Discord.
