Lumo is a mysterious little adventure game. Each level is divided into tiny little rooms so you never quite know what you're walking into next. Additionally, you'll learn several new tricks, or gimmicks, as you progress to help provide fresh gameplay. Throughout the whole game you can expect a lot of precise platforming; so be prepared for a lot of jumping around. Although Lumo may not be revolutionary you'll see fairly quickly that what it does do it does quite well.
There is not much of a story so I won't spoil what little there is. The gameplay is at the core of this experience. You simply must progress room to room. You can only see the room you're in so you never know what you're walking into next. Most rooms will require you to jump around or avoid various obstacles. While the game is fairly linear there are numerous times where you can choose to go down one path or another. By exploring you may reach currently inaccessible areas, such as locked doors, or you may find hidden collectibles.
Platforming is fine and dandy but where Lumo stays interesting is all the gimmicks it throws at you. Zelda also being a third person adventure game, with its puzzle-inspired gameplay, may be a good comparison. You'll find magical boxes that teleport every-time you jump on them as well as boxes that follow you around. You also find a staff and you can use it's light to scare away monsters and reveal hidden platforms to jump on. The platforming can be quite challenging. This isometric style game has a fixed camera occasionally making it difficult to tell where exactly you're aiming for.
Lumo may be a fairly simple looking game but it offers a lot of surprises. For instance, there are a number of wonderful mini-games. Most of these games are only used once but they are super fun throwbacks to classic arcades game. Lumo doesn't take particularly long to play but if you wish to collect and see everything the game has to offer it will take some time. For better or worse the maps, if you even find them, don't actually show your current location. It will be up to you to deduce where you are. Also I'm not aware of any way to warp back to previous zones to hunt down collectibles.
Overall, this is a very charming little puzzle-platformer. The game stays both interesting and challenging without ever feeling too daunting. There are some moments of frustration on the tougher levels but its hard to have a really smooth difficulty curve on a game like this. I only wish it was easier to navigate and find all the collectibles. It would be nice to also be able to replay the mini-games to both get new high-scores and trophies. It certainly isn't perfect but anyone who has a taste for classic videogames should enjoy Lumo.
