Trine is a beautiful fantasy action platformer with a fairytale-like atmosphere, following the journey of three heroes - a Wizard, a Knight and a Thief - in a quest to save the kingdom from evil. The gameplay is based on fully interactive physics - each character's different abilities and tactics can be used to invent new ways to battle an army of undead and overcome obstacles, and restore the balance of the world.
Trine is pretty good game. Climbing on rope then switching into knight and smashing skeleton with hammer is just fun.
Playing time is sufficient and it ends before you get bored. May be this should have little bit more logic puzzles, because this was grinding fingers, smashing skeletons, grinding fingers, ... but it just works fine.
Humble Bundle package is cross-platform and without DRM. This is way how to do business.
