The idea is good. I liked the variety provided by the fact that each house hosts its own mini-game.
The controls are not immediately obvious, but guessable, although not very responsive, probably because it's web.
For the level with 'shooting bats at apples' I really had to read the description below the game to understand what's going on.
Btw, you can attach win build to your game page if you feel that it's much better. And maybe unity export to web can also be improved, at least I can't remember such bad experiences when I did such export.
