One Button Vania

One Button Vania is a Flash game from the late 2000s. It was part of that era where you could find a complete, clever idea in a browser window. The title tells you exactly what you're getting into.

You control a knight navigating a castle. Your only input is a single mouse click. That click makes your character jump. If you're in the air, the same click performs a downward slash. On the ground, it becomes a block against projectiles. Your goal is to reach the end of each stage, avoiding spikes and enemies. The mechanics are simple, but timing is everything. A mistimed block leaves you open, and a poorly executed slash can send you into a pit. The game moves at a steady pace, demanding focus more than speed. It feels like solving a physical puzzle with every click.
