Technos' Taiyou no Tenshi Marlowe: Ohanabatake wa Dai-Panic is a great example.
Its gameplay is difficult to describe, as it's unlike anything I've played before or since. If forced, I'd probably defer to something like "single-screen arcade action," but of course that doesn't give anyone much of an idea as to what they'll experience should they pick up and play a copy of this 1994 release.

Would calling it a cute tower-defense game help at all? That's basically what Taiyou no Tenshi Marlowe is, although even that doesn't completely do its gameplay justice.
For some additional detail, read this 2014 write-up of mine: "Taiyou no Tenshi Marlowe: Ohanabatake wa Dai-Panic is both a mouthful and an eyeful." I'd say more here, but I want this post to focus on the game's adorable instruction manual.

And it is adorable, don't you think? That's mostly due to its wonderful illustrations, of course, but I'd say it's also due to the pastel hues its designers used while printing it.

Actually, it's a good thing those pastels are present, because they really spruce up a few of the manual's handful of humdrum pages and spreads.

The map seen on the page below shows off the many different lands that host Taiyou no Tenshi Marlowe's stages, by the way.

One cool thing about this game's stages is you can tackle them in whatever order strikes your fancy.
