The game has two modes, and many plans for the future.
Hold out for 5 minutes or find an infected one.
Collect coins, they play an important role.
Hide and seek mode, shrink to squeeze somewhere. Use a run to break away. Various objects that you can just climb into for 30 seconds, but they can be checked. Each action costs a coin, so take care of them.
Infected Mode - Figure out how to find the Infected before he kills everyone. Time is not on your side, use your wit.
Maybe you should hide somewhere to watch. Bribing the player is also an option. Maybe voice messages.
Get a lot of new positive emotions.
