Parallel Tank Defense

Mirror your shots, survive the scale up!

PTD is a mouse only twin turret defense game, built for Kenney Jam 2026.

Scale

Enemies come in three growing size classes, the whole 15 waves run escalates from quiet stages to a final gauntlet, and even the camera zooms out as the battle arena grows

Mouse only

Every single aiming, firing, switching formations, even the menus, runs off nothing but mouse movement and clicks.

Symmetry

The two turrets always move as a mirror or a 180-degree rotation of each other, and enemies attack in pairs that only go down when you land a hit on both sides at once.

Description
You're guarding a core with two turrets that always move together, either mirrored across the center (Reflect) or firing in opposite directions along the same line (Crossfire). Enemy tanks show up in pairs, and you want to land a synchronized hit by catching both halves of a pair at the same time. One turret on its own won't get the job done.

You've got 15 waves to survive, and it gets harder the whole way. Every few stages you'll pick a reward, an upgrade paired with a challenge, aimed and locked in using the same twin beam system you fight with.
