### 2/5 — Dumb

*2023-08-19*

This game is pointless. Every enemy that gets past you is just in a loop and respawns back to the beginning instead of you losing a life. If a boss gets past you the wave just starts over. Every time you buy one tower it jacks the price of the next tower up a ridiculous amount so you can’t use multiple towers. Got to wave 14 and only had 3 towers. Stupid for a tower defense game

### 5/5 — Great game to pass the time.

*2021-08-30, version 1.7*

This game is a pretty good time sink if you need that. You can play actively if you want and progress fast or afk if you prefer though it is a bit slower. There are a few things of note. 
Diamonds lose their value pretty quick so there is t much need to invest in them. 
Gold and tower dmg are better than any other investment.
Skill points could be more interesting but they are mostly just pure dmg which is fine for me but other may not like it.

For the Developer. We really need a use all tower skills button because the game quickly becomes use all the skills as often as possible and nobody wants to press all of those skills. Also no matter what items a tower has, whichever one you buy last is pretty much always the only tower doing anything worth worrying about even when all the tower skills are used. The second to last is ok. But that’s about it.

### 5/5 — Great twist in on tower defense

*2021-03-08, version 1.7*

I’ve spent the last 14 days consecutively simply running this app actively while I sleep. It’s super fun powering up the next morning and watching little creeps fall over in a blink of an eye. The twist here is that you can’t lose! That’s my kinda of game!

### 5/5 — Great Tower Defense

*2021-03-08, version 1.7*

Well made, and very fun!
Try it!

### 5/5 — Great ideal idle game!

*2020-09-14, version 1.7*

Great balance and great design! Highly recommend it! It’s exactly the chill type of game I was looking for!

### 5/5 — Amazing game

*2020-03-25, version 1.7*

I was looking for something like that for a while.

Only anlittle bug when playing Ads: ads are playing as portrait instead of landscape.

Thanks all.

### 3/5 — Game is abandoned

*2020-03-14, version 1.7*

This game is good. Has a few flaws. But still addictive. The game has not been updated in 2 years. Interesting that the game has been abandoned. Only two towers of the twenty really do anything. The 2-19 are just there for skills and place holder. It’s hard to progress in this game once you unlock the final tier tower. The wave of monsters health become overwhelmingly difficult. There are lots of upgrades which you use points to activate. It currently takes me an hour to Prestige, and I’ll have to prestige 10 times before I have enough items to upgrade something. 10 times just to progress maybe 5 waves, if that at all. Sadly I will stop playing this abandoned game by the developer. 

Don’t waste money on this game.

### 2/5 — A good start, then disappointed

*2020-02-03, version 1.7*

I started out having fun and getting to know the controls. Then, I tried watching one of the videos, which did not exit gracefully and remained across the middle of my iPad screen with no way to get at the exit button. Not good.

### 1/5 — Rubies not honored

*2019-11-27, version 1.7*

When you purchase rubies you don’t get them. I paid $9.99 for 2200 rubies 3days ago and still have not received them. I want my rubies!!!!!!!!

### 2/5 — Ads

*2019-11-13, version 1.7*

Very qst ad i received was displayed in portrait view while game was in landscape mode....thus...i was unable to click the x out of the ad and had to restart the game.  Pretty junk and low quality if you ask me
