I found it difficult. Maybe it's me or my inexperience with this genre of games.
What i figured out:
Fan is for heat. Microwave is for hungry. Coffe is for sleep(not quite sure of this one beacuse i didin't see the numbers go down). Radio is for boredoom. When flies came: shut down the light. You need to attach one of this things to the power to use it.
I can't stay alive more than 30 seconds, my numbers seems to be ok but i died many times not knowing why..
Fill bars instead of numbers are more intuitive, maybe you can consider to use it if you keep work on this project.
Art is nice. Sound it's really good, specially the "hungry" one.
Overall nice work!
