it's a neat game, similar to other defend the wall with different turret type TD games. the idle progression is slow, and you are rewarded for playing the same stages repeatedly so that you can get lucky and progress. I docked 2 stars because the ads are relentless. every time you want to pick 2 cards, watch 3 ads. 500 gold? 3 more ads. you kill a special drone/boss/elite DURING the match? have 3 ads. I spend as much time closing ads as I do playing the game.

Nice game, however, it uses a lot of battery and runs very hot. The development team would need to find a way to reduce battery consumption and mitigate the heat issue. Not able to play for long before the battery has been totally drained. The game is pretty simple and shouldn't require that much computation. I will upgrade it to 5 stars if the above issues can be resolved.

When choosing weapons upgrades, exclusive cards are drawn that force the player to watch an ad to get the card or giving the player a choice between only two cards during combat. This is a terrible mechanic and a cheap move. Watch an ad or stunt normal gameplay. not for a bonus or a permanent upgrade just a normal game mechanic. 1 star. Uninstalling. W Will never return.
