Looking for a specific lander-game

[corpsicle]

Well, theres going to be a lot of guesses in this request because this was a while ago (mid 80's).

It was a lander game.
Pretty sure the lander was light blue and there was spikey caves in dark blue i THINK on black background.
In fact, when i saw Dangerous Planet i was sure i had found the game.
But as far as i can remember the levels changed, and they dont seem to do that in DP.
Also i dont remember there being a pick-up/drop element in the game i played as a kid.

Does anyone know the game im talking about or is it just my memories distorted?

Could you be talking about "Jupter Lander"?
