i mean yeah i get where TedBrosky is coming from, i would be sceptical if the jam hosts said they will be using the assets for their game and demanded some sort of licensing agreement by entering the jam or whatever.
but yeah most ppl taking part in these here jams publish their entries under open licenses anyway, pretty much anyone can use them if they want. we just have fun and motivate each other to make pixel art, thats all 🦧
