I'm sorry to hear that it didn't meet your expectations. First thing the game shows when you 1st load it is a very basic tutorial perhaps you missed it or it didn't show :l
There's definitely SFX in there, sure it could use some optimization but we tried it on a 8 years old laptop with an iGPU and it ran pretty well.
Yeah we ran out of time to model the kitchen so we left it as it is xD
Cheers!
