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 4 → 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 2,400 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.

Totally Awesome game! Please keep 'em coming like this one.
Excellent TD game/deck builder. Loved every minute of my time playing.
Too clunky and slow.

Fun and has a good amount of content. Ideally get it on sale though.
I originally had a thumbs down for this game, due to a bug that messed up the tracking of the turrets. The developer fixed it, and I havent had any problems. It does change some of the game play quite a bit; but he did what he could as a solo developer, and I'm still enjoying the game. If you dif turret defense, and card collection systems -- there's no reason not to give it a go. its fun.
A puzzle game with guns what more could you ask. Challenging and fun.
A great all around TD game... - lots of game time for the price - different strategies that evolve as you progress - just plain fun - a ton of cards - expert mode is (for me) the best setting On the improve side - bosses should be bigger and badder - feels like there should be a level 6 to use some of the great cards you get on level 5 - the "boards" could be more dynamic or varied - in game info for how mechanics work needs improvement Highly recommend...
Deck Building + TD!
My favorite tower defense since element TD. The campaign is challenging, and very satisfying to beat. If you get stuck on a level there is always the rogue-like to swap to as well. Collecting cartridges, building unique decks, and planning mazes for each map have been some of my favorite aspects of the game on top of it's core tower defense game play.
I liked it. It has been a while, but i remember it working and being fun. Only stopped because I finished the endgame content, just checking in to see if it had any updates since then.
