You started off on top of an alien mountain and explored downward/sideways picking up weird items? I think you were some kind of alien too.
I don't think there were any enemies, but I do remember us getting stuck in holes that you couldn't climb back out of.
There were teleporter rooms (?) that had buttons in alien writing or something that would teleport you if you hit them in the right combination.
The ground was all organic and quite detailed (for just using black and magenta)
Here's a super-quick mock up of 3 screens that I somewhat remember. Note that some of this might be a little off since last time I played it I must have been around 6 years old.
