I managed to only get it started on Linux, on Windows it was not possible for me. I completely don't know what I should do in that game...
After clicking E or G, nothing happened. So I actually cannot play that game.
E is for interacting with cakes and breakable walls(marked by the res carpet), G is for picking up items and placing them( cake slices for fixing cakes). It is an exploratiom game, the objective is to get to the end room.
Okay, It helped
