actually  easy,  you should find some items with (Look For button) and u should make useable with (use button and true tile(place)) if is not ,

for example u found dirt key u should wash for using

you are right, Thank you for your Comment :D

Well you can see your Turn Counter on top of the screen.. If that turn counter hits zero... ITS GAME OVER.... 

Here's what you need to do.

Find the key for the backdoor and car. And escape the house before turn counter hits zero.

The car key needs to be assembled tho.

HINT 1: The first part of the car key is in the fridge inside an ice cube.(use LOOK FOR action while standing next to fridge)

HINT 2:  You need to "Use" that ice cube and stand next to stove to recover first part of the key.

HINT 3: To "Use" any item you need to click that item in the inventory and then click the "Use" action button.
