Fun concept and leaning into the silly alien/pyramids premise with the graphics works well.
The combination of flying around abdudctiong animals crossed with the inventory management is a cool idea. I didn't really bother with too strategic placement of the animals, somehow all the properties of the animals were bit too much to handle, so I ended up sticking them wherever. But that's mostly my lack of patience...
It had some performance issues for me at first (especially in firefox), but giving it some time to load/buffer in Chrome did make it pretty smoothly playable in the end.
