Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 17 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Reviews
A good Tower Defense title that will push you hard (at least for me in the early stages). Initially had troubles, being unable to get close to passing easy on the first level. Turned out that the towers needed upgrades that were not explained in the tutorials - when you click on a tower, a little screen comes up over the tower that has 3 sections - if you double click on the left section, you upgrade; if you double click on the right section, you sell the tower; if you click on the triangular section at the base, you exit the tower screen. Looking forward to battling on!
