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 25 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 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.

Cute game. Yes, it is old! And it is not the most strategic TD on this planet but not everything has to be a competition. I enjoyed the cows and aliens. It was a nice game to play when you just have not much time. I have this game for years and I still play it from time to time (and one day I will have all achievments :D)
One of the most unique and engaging tower defenses I've ever played. The different "lives" system from others in the franchise like Kingdom Rush or PvZ leads to a lot of creativity in map layout, enemy types, and defense strategies. Also, the music is phenomenal, with the main theme being the highlight for me. I left it open on my PC while I went to do something and unironically enjoyed the music playing in the background while I did stuff.

This game is really fun, the raygun allows for so many options in the game, while technically not being required. But regardless the difficulty in this game is really well tuned (which may be the result of having like 15 playtesters), and there's not really unfair moments in this game (except for maid raid).
