When a game comes along with a name like Mourn, it's a pretty safe bet to assume that it's going to be challenging. Not even necessarily in sense that it's difficult to complete, although this puzzle platform game by Keybol will certainly test your skills. But "Mourn" is the kind of title that implies a certain heaviness of theme; the kind of game that wants to make you stop and think, and not just about how to solve it. The protagonist of Mourn finds himself in a place that's dark both physically and metaphorically, and the only one he can rely on to get out is... himself. Specifically, the various copies of himself who lie around, frozen in time, until you press [shift] or down to hop between bodies and animate them. He'll wander around with the [WASD] or [arrow] keys, jump with up or the [spacebar], and discuss his situation as he traverses a dark mine that may or may not be metaphorical, collecting the pickaxes that will help him make his way out. And since there are only so many of him to go around, he'll have to carefully rely on the limited numbers of himself that exist to escape the dark mines. It makes more sense to play than it does to explain, which is good, because Mourn is tightly-designed to try both your reflexes and your brains.
Mourn is not unlike The Company of Myself, in both theme and gameplay. Unlike in the latter, however, Mourn puts a greater emphasis on you having a limited number of copies to work with. Whenever you hop between bodies, your clones freeze exactly where they were in space and become immobile. The puzzles very often revolve around positioning your clones just so to form platforms for you to land on or jump across. However, this also means the levels require a high degree of coordination, both to place the copy-platforms correctly and to jump between them! Mourn is a puzzle platformer that asks you to be equally good at both genres, and since it has tight platforming controls and intuitive solutions, it never asks for too much. However, some of the puzzles do require a fair amount of precision, so it's safe to say it does want you to be a moderately better platform-jumper than a puzzler. As for the game's plot... Mourn is certainly unafraid to wear its theme on its sleeve, right down to its achievements named after the five stages of grief. The game mechanics and the story don't mesh as nicely as they do in some other narrative-driven platform games, though the way the tutorials are integrated into the dialogue is pretty clever. And Mourn doesn't quite feel as thematically deep as some of its compatriots. But ultimately, Mourn still feels like it's coming from a sincere place, and that's especially important when attempting to deal with a sensitive subject like... well, mourning. Ultimately, yes, Mourn is much more challenging as a platformer than it is as a story, and a fine platformer it is too. But there is truth to the tale it tells, and that's still worth commending.
