Ah, the memories! I remember playing this as a kid on my Pentium 1-powered desktop for hours on end and I only had the shareware version (I think it came on a floppy disk with an issue of computer-related magazine). I just loved the scenery (especially this one level where you could see a cobalt-blue sky with a full moon) and the laid-back gameplay (I don't recall it being difficult, but then I played it on 'easy'). It just popped into my head the other day and I couldn't recall its name, but a little bit of googling (actually, 2 minutes) pointed me in the right direction. I don't think I would buy it now though because I probably won't enjoy playing it, which would ruin those memories.
