Jarred Defense

Jarred Defense is a tower defense game about protecting a cat trapped in a jar. You place towers anywhere on each map to shape enemy routes, send them through hazards and create choke points for splash damage. Its strategy centers on planning, placement, items and upgrades, without spells, first-person shooting or random card modifiers.

Shape the battlefield

Maps change as you play. You can force enemies through lava and adapt as heat sources melt ice blocks. Sending the next wave early earns a bonus, with the reward weighted by risk. Equippable items and branching tower upgrade trees let you change your strategy and find different ways to beat the same map.

Enemies have distinct mechanics: some stop to heal, some fly over defenses, some split into more enemies when defeated, and others grow faster the longer they travel in a straight line. Levels also include bosses and mini-bosses, and hazard tiles let you make enemies cross dangerous ground.

Campaign and challenges

The story campaign takes roughly 4–6 hours and uses cutscenes to reveal why Yuki keeps appearing in jars, what happened to the robots and whether any of it might be her fault. Yuki also provides ongoing tactical support, though her opinions are not helpful. Optional challenges unlock new towers and items, and the game includes unlockable cosmetics for Yuki.

Endless and community maps

Endless Mode includes leaderboards. A full level editor lets you create maps and publish them to Community Maps, where you can play and rate levels made by other players.
