Everything is a mystery. Your mother talks to you in the bottom left and is an amazingly nice touch to set the atmosphere. Throughout the game, there's something unsettling about the situation you're in. You slowly learn bits and bits of what has happened as you repair your body, but you never learn the full story. The more you play, the more you want to find out. The ending is quite surprising.
The entire game is set in single tone levels with pretty much everything that moves out to kill you. You eventually gain a gun that basically lets you belch a pixel that leaks rainbow sparkles everywhere. Some of the levels are zoomed out so far that it's hard to tell exactly what's going on, and it'd be nice to be able to zoom in on the minimap, but these are just nitpicks and in no way take away from the gameplay.
The game is a standard platformer with good controls, and fun upgrades. It's great to be able to unlock little parts of your body at a time, and the power-ups feel great. It can be easy to lose yourself in the world, which could have been remedied with an easy way to zoom into the minimap. It's fun to kill enemies, and make your way through, and the game lasts just long enough to keep the levels fun, and leaving you waiting for more.
K.O.L.M. is an amazing story. I wish more games could combine fun gameplay, with an engaging story that just makes you want to see the ending. It's a short game, maybe around 15 minutes of play, but I enjoyed the entire ride. I can't say too much about it, I don't want to spoil the surprises with what the upgrades are and what you can do.
Play K.O.L.M. Here!
