A cat is stuck in a jar. It's your problem now.

Jarred Defense is a tower defense for people who miss the strategic depth of old-school TDs. Place towers anywhere and use them to shape the enemy path. Force enemies the long way around, make them walk over level hazards, and create choke points for your splash damage. No spells, no first-person shooting, no random card modifiers. Just planning, placement, items, and upgrades.

COUNTLESS WAYS TO SOLVE EACH MAP

Build towers. Force enemies through lava. Adapt to melting ice blocks as heat sources reshape the level around you. Send the next wave early and pocket the bonus.

Swap your equipped items, choose different branches in the tower upgrade trees, and find a completely different way to beat the same map.

Enemies will try to ruin your plans too. Some stop to heal, some fly over your defenses, some split into more enemies when defeated, while others get faster the longer they travel in a straight line.

The cat trapped in the jar has opinions about all of this. They are not helpful.

THIS GAME IS KIND OF HARD

I built it because I missed the old-school flash tower defense games that didn't hold your hand. As a result, you’ll probably watch your defenses fall apart more than once. I consider that part of the fun.

ABOUT THE DEVELOPER

Mikolas studied Computer Graphics at the Czech Technical University in Prague. After graduating, he joined Prusa Research, a 3D printing company, in 2017. He now leads the company's Content team.

Jarred Defense grew out of his love for maze-building tower defense games, especially Warcraft III custom maps and Flash-era TDs. Years later, he realized that the kind of strategic tower defense he wanted to play, where building the enemy path is a core part of the game, had become surprisingly hard to find.

“I’ve wanted to make my own game for years, and eventually realized I was in a slightly unusual position where I could program it, draw it, make the trailers, and even do the marketing myself. But the final push was much simpler: I really wanted to play a strategic tower defense with true maze building again. I couldn’t find the game I wanted, so two years ago I started making it.”

Jarred Defense began as an evening project and was developed over roughly two years in his spare time.

Made by one person who just wanted to play a game like this and couldn't find one.
