(Review based on the IFComp version of the game.)
Without reading the blurb, I had expectations of a SF or fantasy work in which Lunium could be the setting’s rare unobtainium used for magical potions or as fuel for FTL-travel. Perhaps it would be mined on a distant moon of an uninhabited planet, or it could only be activated when mixed with dewdrops under the light of the moon.
Not so. Lunium is a combination detective mystery/escape room game. You wake up in a securely locked room, chained to the wall. Your memories are vague and confused, your vision blurred. You must have been drugged…
No points for originality, but it is a solid opening, a staple of IF.
You do remember, aided by the first few objects you find, that you are a detective on the verge of solving a series of horrible murders. Now you must get out and stop the murderer.
Searching the surroundings yields keys and combinations. Unlocking drawers and safes yields clues. Investigating, analysing, combining those clues yields information about witnesses and suspects. This information can then be used to start the cycle anew.
As with a lot of escape games, the puzzles felt forced. It strains the suspension of disbelief that everything you need to escape the room and solve the crime just happens to be lying around (more or less hidden/locked away) in the very location where you’re imprisoned. In this case though, this is justified in the (rather transparent) twist ending. Still, the ending cannot negate the impression of “Oh! How convenient. I’m finding keys all around.” that I had during the game.
Many puzzles do share a common theme (hinted at in the title) that ties them together and gives a nice sense of consistency. (Except (Spoiler - click to show)the colours on the back of the painting associated with the coins in your pocket. Come on, really?)
The character sketches of the suspects/witnesses were intruiging, but too fragmentary to hold my interest in the end. I would have liked more exposition on the relationships between them, and of the circumstances in which my PC came to interrogate or investigate them. Perhaps in some more elaborate flashbacks?
Lunium is aesthetically pleasing, with beautiful and detailed pictures of the room and the details within it. The option to view and enlarge the items in the inventory is well handled and very player-friendly.
A pretty and puzzly Twine to keep your grey cells pleasantly occupied for about an hour.
