Ancient Cosmos A long time ago I had a dream very similar to this, which I'm barely starting to remember now. In my dream it was the apocalypse, and I was strapped down on a table similar to this, and someone told me my only way out was through drilling a hole in my skull (trepanning). It was terrifying, especially since I was very young when it happened. Thanks for reminding me of that interesting dream.
Superb job on the pixel art, and your pixel lighting/shading is really good. The smooth and twitchy motions were well done and give it a good sense of animated style as well as it sets the creepy mood for the animation. The story was well told without any dialog, and comes off quite very enigmatic and ominous as I expect you wanted it to.
Great job on this overall, the retro pixelated animation style has got to be one of my favorites and you pulled it off marvelously, while also portraying a very thought provoking storyline and providing lots of symbolism. As for how I see it could be improved, at the scene where the scientist is marveling over the pyramid structure I think a silent chuckle while slightly looking angling his head higher up would've been a nice detail to add and make the scientist seem just that much more maddened by his quest. Other than adding that one small detail its hard for me to think of anything else you could add to make it better. Maybe I'm not the fairest and most unbiased reviewer but you got my 5/5.
