Penumbra is a first person horror adventure focusing on story, immersion and puzzle solving. Violence and combat is hardly an option - the player has to use wits to guide Philip through his final test, and this makes the series unique in offering a truly dangerous and terrifying experience.
One of the best games I have ever played. For me it is THE definition of the Horror Adventure Genre.
++Enough Object Interactions
++Perfect Dark Ambient Lighting
++Clear level structure
++Scale Perfect (neither long times to walk)
++Physics Interactions(Door Physics)
++Easy operable HUD(Inventory)
-Playtime could be longer :P
++Enough Background Information
++Well narrated with the notes
-More other mediums to narrated the story(Maybe short movies on tv screens)
++Plain and realiable sounds
++Not to much background music
++Terrifiying melody if the monster chase you
But for the first project as a gaming company (if my informations are right) Well done! :)
