In Discord, the topic came up whether the game art has to be selfmade as well.
Given that there are some new devs joining this competition I went for a CC0-licensed art pack from https://opengameart.org/
Someone else went with https://craftpix.net/
Could you state your guidelines using pre-made art?
For sound I would hop to https://freesound.org/
Thanks
