Play Super Mario Battle Online
You shoot enemies, then quickly pop their bubbles before they respawn—sounds easy until you miss the timing. Two-player mode turns it into a frantic race to see who can burst bubbles faster.

Game Overview
Super Mario Battle is one of those weird little Flash games that somehow sticks with you. You’re basically shooting enemies, but here’s the catch—if you don’t pop the bubble that forms around them after they’re hit, they just respawn. Messed me up the first few times until I got the rhythm down.
There are four stages with four levels each, so it’s short but surprisingly satisfying to blast through. The two-player mode is chaotic in the best way, especially if you’ve got a friend who doesn’t mind getting competitive over bubble-popping timing. It’s simple, but there’s something oddly addictive about it.
