Hi, thanks for taking the time to write this, but the conclusion is wrong. I am the sole author of every asset in this pack, including these asteroids.
They were originally made for my game Hope of Humanity back in 2019. The asteroids are 3D models I built in 3ds Max, then rendered and pixelized for games with a similar look. That is why they look like downscaled renders rather than hand-drawn pixel art: that is exactly what they are. It was my workflow, not a sign that the assets were taken from somewhere.
On your specific points:
- Color variants: the recolors are intentional, so you can have more variety in-game from the same base models. The screenshots and description show the full contents before purchase.
- Transparency and edges: the alpha was cut from the original renders, which explains the edges you noticed.
- Pixel versions: they work best at small sizes, as you noted.
Not liking the quality is a fair opinion. Saying I don't have the rights to my own work is a different matter. If you have found these assets published anywhere else, please share the link. Otherwise, an accusation of theft is serious, and I'd ask you to edit that part of your comment.
