That was some fun exploration and some nice platforming. I think I got 4 artifacts. I can move blocks, climb vines and jump. I think I am missing a powerup to maybe turn blocks on?
Everything looks and controls great.
It would really benefit from a map. I am currently hopelessly lost and going around in circles. A map that lets me know where I have visited and what is available to visit would definitely improve the experience.
Looking forward to the next update!
