Disaster Simulation [Escape]

Sirens are blaring. Some sort of catastrophe is imminent!
The only way to survive is to enter a shelter!

Escape exits are randomized from 1 to 10 locations.
You get 1 point for each time you return alive, plus a bonus for opening the chest.
Use points to buy items.
You will get 100 points for the first time only.
If you have an escape radar or transparent glasses, you can find the entrance quickly.
Be careful, the items will disappear if you fail to escape.
