During this jam I used Unreal Engine 4, which is probably a bit overkill considering the limitations, so I figured out that since apparently I was the first one to use it I could share the template, just in case someone wanted to make a game with it:

The license is Creative Commons Zero v1.0 Universal, that means that you have the permissions for private and commercial use, modification and distribution, and that you don't need to give me credit in any way. Obviously credit is appreciated, but feel free to use it however you want.

If you have any question just post here and I'll answer as soon as I can, and let me know if you make something with it!

Enjoy!
