Extremely Grindy

Be prepared to lose a level 50+ times in a row. Improvements are infrequent and so miniscule they will not sway your luck in battle. RNG played a huge role in your potential success as well. If you draw a few wrong cards early on your run is doomed. Would be much better with more meaningful upgrades. But then I guess you wouldn’t have to spend money constantly to win. It looks great and in the rare moments when you feel a bit powerful it feels pretty good too.

Красивая идея, которую угробили

Я большой любитель игр подобного жанра. Но то, как реализована конкретно эта - просто ужас. Не представляю как мало надо разбираться в том, что ты делаешь, чтобы в каждом аспекте умудриться выбрать максимально нелепое, неудобное и бесполезное решение. В этой игре от игрока не зависит ровным счетом ничего, игрок может просто тыкать кнопки наугад и все равно либо победит, если подкрученный в худшую сторону рандом в этот раз на стороне игрока, либо проиграет несмотря на все свои попытки строить стратегии и обдумывать каждое улучшение. 1 звезду накинул за понравившийся визуал. Но в остальном это даже не игра - это интерактивное кино с иллюзией участия посредством не влияющего ни на что выбора

Too many ads too quickly!

Looked like a fun game. But it served me an ad just barely 10 seconds in to playing the game. So I immediately deleted it. You have to give people some fun first!

Fun but impossible.

Progressing in this game without paying is kinda impossible. Not even a glimpse of hope.

Painfully slow without spending

There isn’t what I would say as strategy in the game, but rather luck. And then slow experience, slow cards and upgrades, and face defeats 90% of the time or more. Lose, get a few things, get a tiny bit better, upgrade, lose and upgrade a tiny bit and try to win levels. I am on stage 12 after maybe 6 hours of playing. Deleting this. Was fun for a minute.
