› Loop Tower

what is Loop Tower?

Defend against enemies traveling a looping path by placing towers and excavating to extend their route.

Enemies follow a carved loop path in the underworld, and each completed loop costs you health. Place towers to stop them and excavate to lengthen their path, increasing your chances of survival. The goal is to last at least five minutes in this incremental tower defense game made for GMTK 2025.

It sits in the Management corner of the genre. Like most idle games it runs on a simple loop — earn, reinvest, automate — but the depth is in how long that loop keeps unfolding. Expect to check in, make a few decisions, and watch the numbers climb whether you're at the keyboard or not.
