Descend a seemingly-endless tower, wielding an arsenal of deadly ninja weapons and attacks, as the fearsome Crimson Ninja. This 2D action-platformer uses ninja magic to generate every tower randomly, so no two adventures are the same! Based on the hit Flash game from developers Megadev and Adult Swim Games.

Trauma (styled as TRAUMA) is a graphical adventure interactive fiction game developed by Polish programmer Krystian Majewski as part of a thesis project, and released in August 2011. The game is based on a woman that has suffered a physiological trauma, and has been languishing in several dreamscapes while unconscious and hospitalized. The player resolves these by using both point-and-click and gesture-based actions to move about the dreamscapes, composed of photographs with digitally-altered features, to complete a certain task.

The Tiny Bang Story is set in a fictitious world that is hit by an asteroid, leaving you to literally pick up the pieces and put it back together. Over several chapters, you need to rebuild machines and solve puzzles to find all the pieces you need to rebuild the world.

Botanicula is a point-and-click adventure game developed by Amanita Design. I'm not even convinced it's a game. It's definitely point and click, and it might be an adventure, but game I am not convinced about. You click on random things until something happens, and then you ask 'was that actually what I wanted to happen?' before realizing that no, you still don't know what the point of all this even is.

On a bright note, wikipedia says that Botanicula is helping the World Land Trust to protect hundreds of acres of rainforest.
