The Darkside Detective and Definitely Not Fried Chicken

Two games starting with the letter "D".

The Darkside Detective

This small pixel point and clicker has you play the titular Darkside Detective, which includes cases involving ghosts, zombies, and things not of this world! Yet due to the awesome writing and humor, it's always funny and never actually scary. Each case is also self contained with all the items you need to solve it being at the scene, along with easy hints on how to proceed built into the character's musings (so you don't have to press a big "hint" button or anything). On top of all that are some good ideas making this a really easy game to recommend. 

Definitely Not Fried Chicken 

This voxel game is a management one, starting in the tutorial chicken shop where you need to make rooms and decorate them with functional equipment like toilets in the restrooms and friers and chicken huts (for freshness) in the kitchen then hiring staff to handle said equipment. The colonel fires you right after the tutorial though so that you can go use your newly learned skills in building some other enterprise... drugs!? Yep. Not really my style so this one is a pass for me.
