The sound is absolutely captivating and the gameplay oddly addicting. It's showing how many darn games I've played these last 13 months because I was able to recognize this as essentially a clone of Caverns of Mars/Mars Mission II (just realized I never played the first Caverns of Mars! added to the backlog oh boy haha). But this still stood out, like Mars Mission II, for its tight controls and addicting gameplay. Can't highly rate a clone, though, and Mars Mission II is a great game so just play that instead.

Edit: Hmmm, well wait, I hadn't rated Caverns of Mars, but I was definitely thinking of that one--not Mars Mission II. Cuz I guess Mars Mission II switches to horizonal scrolling, looks a lot like Scramble surprised I rated it so high. Hm. I wonder which mars/cavern themed game (likely a clone of the original Caverns of Mars) I was thinking of, then, since I apparently hadn't already played the original Cavers of Mars.
