How it feels

A calm, low-stakes tower defense where you incrementally upgrade towers at your own pace with no wave pressure.

What players say

Players are split on whether this is an idler or a puzzle game, with many calling the tags misleading. Campaig is short at 33 levels and the prestige system feels unsatisfying. Difficulty spikes sharply around a few key upgrades, and levels force repetitive re-deployment. Some enjoy the strategic problem solving, others find it boring.
