Original gameplay ideas

In the meantime, as most of the more or less large companies make monotonous games, independent developers are looking for, inventing, trying new opportunities.
Under the cut a small selection of games in which there are fresh ideas.

Unfinished Swan : around monochrome space, the player bullets balls of the opposite color to mark the surface. The game is in development.


Flipside
The mod for Half-Life 2, the main character is crazy with a split personality, you can turn the world on the other side. And there - it's different.


Tempo
The player controls the lady in an elegant hat, moving in a wheelchair, but with super-abilities like telekinesis and "out of the body." The video is nothing special, but the idea is rich, I think.

World of goo
But this is not just a curious concept, but a successful game, with interesting tasks, stylish graphics, and atmospheric music.

Yes, that there, about her recently wrote .
In this case, finally, I will mention the project Experimental Gameplay , behind which stands Kyle Gabler, one of the creators of World of Goo.

A couple of flash games on the topic of time travel from CharnaD and nooze : about robots (Chronotron) and cursors (Cursor * 10)


Update 3: how could I forget about Patapon! thanks megatondetrua
Very stylish game, controlled by a tribe geezer with the help of music. One of the games for which it is worth buying a PSP.


This category is worth adding Audiosurf - load music and go on the track, collecting multi-colored cubes. Thank you anatoly_rr for the reminder.

I also remembered Loco Roco for PSP, tilting the game world and rolling a pretty creature.
