Version 0.4.5
performance_and_bugsadvertisementsnotificationscontentFun & cute. I haven't ran into an intrusive ad; all ads I've watched of my own volition. The rewards for said ads are quite generous. It is fun watching your units evolve into hardened soldiers as you upgrade (for example, the warriors get a headband after a while- so edgy!) Some cons: Some lag, especially with teslas/thunder totems against a large horde only 2 Heroes for free to play players, total Some notifications don't go away- my Hero page tells me I can do something, but I can't.

updates_and_maintenancemonetizationpaymentfeature_requeststhe game itself is fantastic. 5 stars. However I have an extreme issue with their recent updates. they recently tailored their shop against play pass members. they did this by removing everything we could 'purchase' from the store as well as the ability to use ad skips to double rewards. I can use my gems to buy things in the store, but I can't buy any new gems or bundles. including the new hero. I am hoping they fix this, even if just by leaving play pass itself.

customer_supportperformance_and_bugsupdates_and_maintenancegame_progressionTetris meets merge games. It's fun! I originally rated it 4 stars because of UI annoyances and there being a lack of stat info available. I reached out to support about a few bugs and was really happy with the response since they're already working on fixing them. It's a fun game and there's more to do now. The team has made a lot of improvements and I'm enjoying the progression. I really like the game and I stuck around hoping there'd be updates.
