Batdog

Batdog was one of those games you'd find in the late 2000s, tucked away on a Flash portal. It had that simple, cartoonish look common to a lot of browser games from that time. You played as a dog dressed like Batman, which was the entire premise.

You control Batdog, who rides a hovering board. The main goal is to shoot the green kryptonite shards floating in the air. You use your mouse to aim and click to fire. The board moves automatically, so you're mostly focusing on lining up shots while avoiding obstacles. The pace is steady, but it gets trickier as more shards appear. It feels like a straightforward shooting gallery, a quick test of your aim and timing.
