Zigzagnoff Defense is a hybrid tower defense and shop-merge game made with LittleJS. Enemies march down a winding zigzag trench toward your Steam Bastion. Between waves, you roll the shop to buy towers and runes, place towers on top of the trench barricades, and merge matching towers to upgrade them. How it works: Merge & Fuse: Combine two identical Tier 1 or Tier 2 towers to level them up and draft an upgrade perk. Combine any two different Tier 3 towers to create one of 15 Tier 4 cross-fusions. Defend the Barricades: Enemy Saboteurs will try to blow up weak points in the trench walls. If a barricade breaks, enemies get a shorter path to your base and any tower sitting on that spot is disabled until the next wave. Stack Status Effects: Socket runes into your towers to stack Burn, Bleed, Acid, Static, Chill, and Hex on tougher enemies, tanks, walkers, and airships. Daily Seed: Features a tutorial run and a daily seeded map layout with endless waves. Controls: Mouse / Touch: Click or drag to buy, place, move, and merge towers. Drag the background to pan, scroll to zoom. 1 / 2 / 3: Pick upgrade perks. ESC: Pause / Menu. Entering Wavedash Category of the jam. Itch link: https://fatalexit.itch.io/zigzagnoff-defense
