About

Pest Control Weasels is a fast-paced arcade puzzle game where you control a weasel trying to catch pests in a series of increasingly chaotic rooms. The game's mechanics are immediate and physical — weasels move, pests move, and collisions determine success.

It was built for the JS13K game jam, which limits entries to 13 kilobytes of JavaScript — a constraint that forces remarkable creativity. The result is a tight, focused experience that packs genuine fun into a tiny footprint. The simplicity of the premise belies the frantic energy of play.

Short rounds and immediate restart make Pest Control Weasels perfect for the kind of 5-minute burst you get from a coffee break. Each level is a fresh puzzle-action challenge that you can clear or fail quickly and restart without hesitation.

How to Play

• Move your weasel using arrow keys or WASD.
• Chase down and catch the pests before time runs out or they escape.
• Some pests move in predictable patterns; anticipate their path.
• Clear all pests in each room to advance to the next level.
• Avoid obstacles that block your movement or slow you down.

Tips

• Corner pests against walls — open space lets them dodge you easily.
• Learn each pest's movement pattern before committing to a chase.
• Move diagonally to cut off escaping pests faster.

History

Pest Control Weasels was created for the js13kGames competition, an annual game jam that challenges developers to build games in JavaScript under 13 kilobytes. The competition has produced hundreds of inventive small games since 2012, pushing creative constraints to their limits. The 13KB limitation requires everything — graphics, sound, physics, logic — to be extraordinarily lean, resulting in games that are models of concise design.
