Do you remember Manic Miner? I bet my floppies that the programmers of Realm of the Trolls do. To be fair, it is slightly more graphical and atmospheric than that, but it is "one of those sort of games" with a spot of Apple Panic and Dig Dug thrown in.
If you are fluent in French, Spanish or Italian you might be able to read the instructions. The English version doesn't make any sense.
From what I could understand - and I am open to suggestions you assume the role of an elf whose duty it is to enter the treacherous troll tunnels to steal back all the amazingly fabulous elven relics which the avaricious if somewhat tasteless trolls have purloined from the elves some time in the past.
The caverns take the form of a series of halls. There are quite a few of them - a whole separate data disc full. In each hall the elf must collect all the valuable elven treasures - he may also take some of the art treasures the trolls have collected and pick up some healing potions before locating and leaving via the exit passageway.
To assist in moving around the hall there are infrequent magic portals which instantly transport you to the destination of your choice. In some halls there are even lifts pulled up and down by small bats which obviously don't have a very good union.
Another form of public transport is the wagons which perpetually run up and down the tracks in a few of the halls. For the pedestrian there are always the ladders.
One of the hazards of being a cave robber is encountering the owners, in this case the trolls, who carry around large baseball bats and attempt to play nine innings with your head, which is decidedly bad for your elf (sorry).
There are several ways to deal with them. You can use your mental powers to stun them, use your awesome magical powers to blow a hole in the floor and kill them or, by far and away the best, you can leg it.
A very annoying features is that the elf can be controlled by joystick but you must click the mouse to use mental powers and magic.
The animation is not up to much, though the scenery of decomposing walls and lichen-covered masonry is quite effective at building up the dungeon atmosphere. The same cannot be said of the sound effects which, aside from the thunk of bat on skull, sound like they might have loaded wrongly.
If you find the puzzles boring, or if they are too difficult, you can always use the scene editor. This, as it turns out, can be a lot more satisfying that playing the game. As well as all the usual stuff for building ladders and walls, you can change the personality of the trolls.
Only to be recommended if you have difficulty finding something to do on Sundays.
