Trine is a hack-n-slash, puzzle platformer set in a fantasy world. While the graphics are 3D, the gameplay itself is sidescrolling and 2D. The setting is absolutely gorgeous with dungeons, lush plant life, water, and more. In Trine you must sometimes overcome puzzles, usually in the form of figuring out how to reach a particular place. The undead will try to stop you and are fought in a typical hack-n-slash method – run up and hit them with a sword!
Three characters are presented to the player, the Thief, the Wizard, and the Knight. Each has different abilities that allow the player to solve puzzles in different ways. What’s interesting about Trine is that the player can switch between any of the three characters at any time (provided the character still has health). Each character has his or her own life and energy bars. The Thief can shoot arrows and use a grappling hook to reach high places or to swing. The Wizard can create crates and planks (usually used to help reach something, press a button, or as a counterbalance) and can levitate and move objects. The Knight can perform melee attacks with his sword and hold up a shield to protect himself. Many puzzles can be solved in different ways with different characters. This was of particular enjoyment to me because while trying to solve a puzzle I sometimes die, leaving me the two other characters to solve it and forcing me to rethink my solution.

 
The music and sound effects are appropriate and nice, and the voice acting is great. The characters don’t speak much, but it’s nice when they do, and the narrator does a superb job at telling the story like a fairy tale. The writing is nice, and the story more than sufficiently supplies motivation for the game.
Adding more depth to the game, Trine also features experience which can be collected. Each level has a set amount of experience, and when collected, experience is applied to all characters equally. When the characters level up, the player is able to pick skills to improve. In addition, equipment can be found in the levels. The player chooses which character to give the give the equipment, providing the chosen character with a bonus.
Trine features simple, enjoyable combat, fun puzzles, a beautiful setting, and an interesting mechanic (character swapping). These are all aspects of a great game, so it’s no surprise that I’m impressed with Trine.
