Pretty Cool. Loved the visuals! Couldn’t really figure out what the last artifact meant. After collecting the three I tried to search for another of the openings, to see if I could find the egg(symbol depicted in the artifacts). But, after finding it, there was only a black-screen, don’t know if it was on purpose though.
Apart from that it was super cool. The game ran smoothly and it was pretty scary, especially the serpent level.
