Regarding your game, some additional feedback during the tasks would be nice, other then that, i'd say this type of game would require a lot of content to be interesting to play, or have another parallel (gameplay)loop to apply how well you have done during the minigames.
The theme is present, but only in background story
Playability is fine, no complicated controls, simple gameplay
For cleverness, there isnt anything special/unique, could have been there with some unique minigames
Artistic style is alright, the looks are consistent, though for a shadow government game with dark themes, the game is rather bright
