This game is super fun, and has a good bit of strategy. I’m Lv. 18, and the game keeps increasing in gameplay depth. That being said, I wish there was an infinite mode where enemies come in increasing size and you can buy more land to build on. (ADD IN FUTURE UPDATE PLEASE!!!) Even better would be a mode where you have to pay a gem fee to play and the player sets the parameters (size, reroll Lv., trees, ect.) One final, ultimate game mode would be PVP, where players would get gold by sending troops from their buildings to the other player’s buildings by TAPPING THEIR BUILDINGS (devs take note) to add yet another layer of game strategy.

Great Game But Has Bugs and Too Many Ads

Great Game Bad Defects
I got this game a couple days ago and I love the gameplay. The combination of resource management, Tetris style puzzles to try and fit as many buildings as possible, and the auto-chess style gameplay is amazing. On top of that the upgrade tech trees for everything feels good. Gameplay wise I have no complaints. Only if the game ran as intended at all times. The game tends to glitch out really badly if you tab out of the game. Not even if you got to another app. If the game isn’t continuously running on your screen it glitches out. You then need to shut down the game and relaunch it. Sometimes it remembers the wave you were on, and sometimes it doesn’t. I would recommend a fix for that ASAP. The other thing is, the ads go on for too long when you click the option. Have the same ad on repeat and run 2/3/4 times in the ad break is ridiculous. Either short the time to where one play through is enough to get the reward and skip or have fewer of them.

The game starts so fun but soon you realize the game is the same and it’s all about the ads. I’m to lvl 70 and it’s still 10 or 13 waves. The augments are the same. And if you want good augments you have to watch the ads. Though I’ve played watching the ads vs not watching the ads and the it’s only slightly more difficult to beat without the ad upgrades. But if you don’t watch the augment ad the game gives you a forced ad anyway. Funny the “remove ad” ad even states that it only removes forced ads. The characters move slow, but you want to speed up the game then you have to buy the speed up. There is a limited amount of buildings and a limit number of times you can merge them but with only 10 or 13 wave I still haven’t got to the top merge. The enemies are all the same though sometimes the skins change. So it’s fun to try and fit all the buildings on the board but there’s no strategy other than getting buildings on the board. I don’t have to choose what buildings base off enemy just fit it on the board. Improvement ideas: change the board shape and size. And more diversity. Less ads

This game is intentionally convoluted. If you are good at this game, that is legitimately cool. I have two stupid games that I am intrinsically good at. If you are not exceedingly good at this game past the first hour and a half, give up. Besides, there are more ads than usual, and some are an unskippable full minute. There is a couple events that set the game back early on, and they basically require you to use ads or “gems.” I can only imagine that this will continue exponentially. There are far more time wasting games out there with better ad to reward values. If you want to find your game, try this one, however know that it doesn’t get better than about stage ten. To complain without giving solutions is basically whining: if this game gave away the “2x” speed multiplication instead of hiding it behind ads / rewards, then it would be quite a bit better. Still charge for the “3x” multiplier, but give the options between “slow as heck” and “what it should be.” However, with this niche that this game fills, that may drive away swingplayers quicker. Shrug.
