If you're looking for an ethereal gaming experience, give Glum Buster a go. It's a very odd platform game that comes with very little explanation, forcing you to experiment to get through the game.
It's very difficult to describe what's going on. The game starts on a rainy street, and your shadow suddenly turns to flame, revealing a door that takes you to another world. Why, or for what reason, is unclear!
The graphic style is striking, and the mouse and keyboard control works well as you interact with the environment to aid your progress through the various levels. If you enjoy a challenge, Glum Buster will suit you, but some people might find all the mystery a turn off - if you get stuck, there's nothing you can do!
The game is not hard in terms of skill, it's more puzzle based, and getting through some of them will no doubt take some time. You'll need your thinking cap, and a great deal of patience, but it's rewarding in the end.
Glum Buster is a truly strange platform game, but for anyone looking for something a bit different, it should hit the spot.
