Great story, There are several idea i can suggest to you:

1.when players want to hide inside the sewer tunnel i feel pressing Q key button is quite uncomfortable, i suggest pressing W key is more likely comfortable.

2.Instead of W and S button key YOU can apply Q,W,E,R,T for selection button key.

3.You can add information for the... what is that call?? lets just say like hunger bar, stress bar, bronze coin, silver coin, gold coin, ration, est. 

4.How did they give ration more up or less each after working?? im so confuse, may be you can add the information like why they give the ration less or more.

6.add "privilege System" and "Suspicious DAC bar system" for the players? 

*Privilege system: when the Players hit 50% of the loyalty and can prevent the loyalty from decreasing for 3 Weeks, The DAC give privilege, They will give more ratio or increase the wages.

*Suspicious DAC bar system: when players hit the 50% loyalty But can't prevent the loyalty from decreasing for 3 weeks, the player will be questioning by the DAC.

Thats all suggestions from my idea, hope you read this. the game is good and the design, Im always waiting for the full game release :)
