Hi Niko,
You can download the assets from the resources of one of the first lectures, and you may use them for free in your non-commercial, unpublished game. If you want to publish your game, you’ll either have to purchase the asset, or you could replace them with free assets.
Free assets can be found here: https://www.kenney.nl/assets
Also please feel free to ask our helpful community of students for advice in our official Discord chat.
