In Popa Night, you are a cannon that shoots bullets to pop bubbles. Your goal is to pop the most buttons with the least amount of ammo in the shortest length of time. Every level offers a new challenge. Some levels will have little boxes that will catch your bullet and stop it from ricocheting. You want to bounce the bullet as much as possible so it hits as many bubbles as it can. Some bubbles get trapped in walls or or hiding around solid objects so they cannot be hit directly. Popa Night has forty five levels to work through and you can reset any time you don't like your progress.
