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): 0.14/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 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.

Defend Your Life: TD to całkiem przyjemny tower defense z nietypowym pomysłem na przeniesienie walki do wnętrza ludzkiego organizmu. Obrona przed wirusami i bakteriami oraz medyczna stylistyka wyróżniają grę na tle wielu podobnych produkcji. Mechaniki są proste i łatwe do opanowania, ale kolejne poziomy potrafią dać trochę satysfakcji. Nie jest to najbardziej rozbudowany tower defense na rynku, jednak jako mniejsza, luźniejsza produkcja sprawdza się całkiem dobrze. Prosta, sympatyczna i ma swój pomysł. Można spokojnie pograć – polecam.

This game uses the Kingdom Rush series as a template. It has similar layout and logic, including heros, tower types, paths and upgrades design. The graphics are very good and add to the enjoyment of playing the game. It also has its own innovations that all work well, making it something more than "a game you have played before". It takes a lot of talent, skill and programming to put out a game like this one. It should be noted that this game is pitched to be more difficult than the Kingdom Rush games. I am not sure why they did that, but even the "easy" takes work to get through. This is so after you have gone back and done the rounds on "Medium" and gotten enough strength to move forward. It is slow to move on. Maybe that's not all a bad thing, but there is a lack of balance between progress and difficulty. Also noteworthy is that the upgrade path does not have as many steps as in other games of the same type, including Kingdom Rush. The number of towers is limited to four, but they can be upgraded to newer and different versions in some cases. This may be okay, because, as I understand it from my own experience, people seldom utilize all the towers that are offered. They use a few that they are comfortable with to win the game. Speaking of my personal experience only, I found the game to be really good, but not quite the level of enjoyment from the "Kingdom Rush" games, after which it is modeled. The bottom line is: If you like the Kingdom Rush Genre, then you will like this game too, but with more frustration.
bağımlısı oldum sinir hastası etti beni ama çok iyi :)
It's a traditional tower defense. You place your towers in fixed spots and upgrade towers. In addition, there's abilities you have to activate constantly during the run. There's also a hero you can place down like a tower. UI & cartoon is ok. Windowed mode available. It's quite difficult. You will need to redo previous levels to get more consumables, hero XP just to get past maps beyond the first two - there's quite a bit of grind. This is ok if you don't mind grinding the same map over and over again. You will get most of the achievements just by grinding. The grind made the game feels like a mobile fremium port, where the difficulty ramped up so you will buy MTX consumables or grind for free. If you don't mind that, give it a go. For players who don't mind grinding the same maps for incremental upgrades. Not for me.
[h1] "Защити свою жизнь"[/h1] [u][b]Башенная защита в локациях организма человека с врагами в виде бактерий.[/b][/u] С самого начала заинтересовала идея проекта, поскольку было очень интересно как ее смогут обыграть разработчики, но получилось ли у них это? Каждый уровень - это какая-либо часть организма, например 1-й уровень "Глотка", а последний "Мозг". Наша задача защищать "жизнь" человека от бактерий посредством расстановки башен, которые будут с честью уничтожать врагов. К сожалению, с вариантами башен или то, чем они стреляются решили не креативничать, поэтому здесь будут обыкновенные "Пушки" и "Тесла башни", но конечно же, на этом перечень не заканчивается и будут еще всяческие постройки, которые будут разбавлять геймплей и дарить вам пищу для ума, в плане того, какую башню куда "выгоднее будет" поставить. Игра оказалась довольно сложной. Как и чаще всего это бывает, первые уровни вы пройдете с удовольствием и не особо напрягаясь, но ближе к середине начинается сущий кошмар, особенно, если вы новичек этого жанра. Но также, со временем, вам дадут уникальную боевую единицу, у которой вы сможете прокачивать характеристики и лично сами управлять ей по ходу боя, что добавляет элементы RTS стратегии. Также и дадут возможность покупать временные, разовые улучшения за внутриигровую валюту, но понадобятся они вам только в случае того, если вы не можете продумать истинную стратегию боя, поскольку при верной расстановке можно обойтись и без них. Игра затягивает и в ней вы сможете провести большое количество времени, поскольку каждый уровень, коих здесь 17, вам придется перепроходить по 3 раза на разных сложностях, а делается это для того, чтобы как минимум получить материал "Таблетки", за которые вы сможете покупать постоянные улучшения для ваших башен или прочих активностей, а как максимум, чтобы оправданно считать, что вы полностью завершили прохождение игры. Здесь вы сможете найти положительные эмоции, если вам нравится этот жанр и даже если вы в этом новичек, но своей сложностью игра может оттолкнуть слабонервных и не усидчивых игроков. Лично я, искал для себя недолгую и ненапряжную игру, в которой я в теории, не должен был надолго задержаться, но игра меня увлекла и решила иначе.
You have to mute the game via the in game sound icon to get more fps... Never ever have I seen a game with such a problem. DEF not worth 10 dollars!
I absolutely do NOT recommend this ♥♥♥♥♥♥♥♥ game, I got all achievements and I only have this many hours because of SAID achievements. What made this experience so terrible you may ask? Well, not only was I mind-numbingly trying to get the achievements, the stupid music score playing NONSTOP REPEAT and having to listen to my NOW EX HATE ME DURING OUR RELATIONSHIP BECAUSE I WAS ♥♥♥♥♥♥♥ PLAYING THIS STUPID ♥♥♥♥ AND NOT GIVING HER ATTENTION And by golly this did NOT make the experience anymore fun. I do believe this game had a hand in ending my relationship. Maybe, I am the problem. But maybe it isnt the break ups that truly matter but a break up of plaque and harmful bacteria is what truly matters in living life. fk this game bro.
Have you beaten all Kingdom Rush games and wish there were more? Then this game is for you.
Za mě to je jedna z nejlepších, ne-li nejlepší TD hra...a to jsem jich moc nehrál
