It reminds me of Tasty Planet, but you play it from the perspective of a scientist. I wish the game was a bit faster and I wish the player would get more feedback when keys like E or Z are pressed.
Since you were using Unity, here's a tip for improving the graphics of the game: If there are low resolution images in your game, don't forget to set the compression of the image to 'None' and the Filter Mode to 'Clamp'. That way the textures won't look blurry at all.
