No, they are there for illustrative purposes, there's a list on the description of the project specifying exactly what's included on this asset pack, feel free to check it.

I'm thinking on expanding this with enemies, more biomes, etc. when I have the time, anyway, those new assets will probably be sold as standalone asset packs. If I happen to upload more content on this style I'll let you know.
Feel free to drop a video of your game here, I would love to see it.
