## What is Non?

Space is a dangerous place—and every second, the threats beyond the stars get bigger… So your mission is to keep up with the infinite invaders and endless fun of this idle tower defense game! 

Endless waves of space invaders will clash with you non-stop on their mission to attack Earth. Command your spaceships to act as defense towers and shoot ‘em down as you gather Gold. Over time, your foes’ power will grow more epic, but laser guns aren’t free! You’ll need to spend that Gold to upgrade the attack power of your spaceships to overcome bigger and bigger challenges.

But no matter your strategy, even the most epic tower defense is eventually doomed, and the aliens will get through… But that’s just the beginning of this non-stop battlefield!

Whenever invaders slip through your idle tower defense, the challenge resets, but each tower defense upgrade remains. That means you’re free to keep building each tower to shoot aliens with endless power and handle even bigger aliens than before! You can even close the game and come back later to gather your Gold. See just how strong you can get, and how many of the infinite waves your tower defense can hold off! 

So assemble your star force and launch your epic space mission now!

Features:

• Command your space fleet on a non-stop mission to free Earth from infinite invaders, and become the Hero of the Galaxy.

• Your spaceships shoot even while you’re idle, but you can add the power of strategy by tapping the invaders you want to attack and shoot down most.

• Enjoy the addictive fun as you’re free to customize your tower defense and upgrade it to shoot the aliens with more power and unlock epic new strategy options.

• Collect a fleet of 20 spaceships for you to command and upgrade, each with its own unique design.

• Unleash over 6 epic attack powers to help you shoot down the infinite invaders from space. You might find the endless strategy of the stars addictive!

• A unique neon art direction for the aliens, your epic fleet of spaceships, and the endless stream of laser power resulting from the clash between them. 

• A colorful UI with one-touch command controls that casual idle strategy fans will love.

• Enjoyable laser sound effects that keep the non-stop idle action addictive.
 
• An addictive mix of tower defense, infinite space strategy, and classic arcade action.

• One touch lets you command all the epic action of your mission to save Earth from attack.

Perfect for fans of tower defense, infinite aliens, spaceships, endless strategy, addictive fun, non-stop idle games, being an epic hero of the galaxy, arcade game action, one-touch controls, and casual experiences of any kind!

### 1/5 — dumb

*2022-08-05, version 1.1.2*

Extremely boring and repetitive. After the first 80 waves you just get stuck doing the same thing over and over again. For reference, I am currently stuck on wave 80(in the second round)because your supposed to play the level over and over again so much that you level up and finally win. Well guess what? I am not gonna sit down for 4 hours and do the same thing over and over again. There’s hundreds of other games much like this one with one difference.  They are better. Go find them and play them instead of this crap.

### 1/5 — Suspicious

*2022-08-04, version 1.1.2*

Was enjoying this game for a while but I have abruptly decided to stop playing it due to suspicious activity. Upon launching, it requested data from my clipboard. There is no reason this game should ever need that. Ever. Buyer beware.

### 1/5 — Thanks for reading

*2020-10-25, version 1.1.2*

I really like this game.

Uninstalled due to forced ads and no way to remove them.

I would reinstall and rate much higher if the forced ads were removed either by making the ads manually activated on the users end for benefits or even a way to remove them for a dollar or something.

### 2/5 — Ads ruin gameplay

*2020-09-06, version 1.1.2*

Fun game, looks nice, but ads happen at random.  But when they do, they take your entire screen while the game continues to run, making it to where you can’t defend yourself. 

Most of the ads I had you couldn’t cancel until much later into the ad itself, and there’s no way to remove ads, so you’re pretty much stuck with them.

### 2/5 — Good premise ruined by slow game speed and ads

*2020-05-31, version 1.1.2*

This game could be pretty interesting, but it has three problems. One, the weapon types aren’t meaningful choices. They are all the same autoturret, and the different charge-up abilities don’t meaningfully vary as far as effect on the game because the enemies are all essentially the same. 

Two, there is no option to speed up the game. Progressing through the levels is really boring. There is a prestige mechanic, but you can’t do it often enough, and besides, you’re limited by how quickly the level sends bubbles. There’s no way to send the next wave early. 

Three, there are way too many ads and no option to pay to remove them. There are ads every few levels ads to turn on a 180 second coin boost (you need this to progress) so you will be viewing ads about 20-30 times an hour. It’s too much. Progress without ads is slower than watching ads. 

I think this game has potential if these things are addressed.

### 2/5 — Ads

*2019-12-01, version 1.1.2*

Ads in the middle of playing are a huge turn off, especially if your trying to make a first impression with your game.

### 3/5 — Ads ruined it

*2019-07-11, version 1.1.2*

I used to enjoy this game...but now the pop up ads have destroyed it. 30 second ads every level stop you from even completing the level the first time. I get trying to make a little coin, but the ads are ridiculous, the ones up top are fine but every level another stupid video ad for another game is a joke. Way to ruin your game.

### 3/5 — fix your ads

*2019-07-01, version 1.1.2*

with all of the random pop-up ads that appear in the middle of a level and make you lose, youd think there would be an option to remove them. i spend a lot of time on this game so im trying to not give a bad review, but why have so many ads if theres no option to get rid of it? i wonder if you even want people to play this game longer than 10 minutes, cause this and the near impossible-to-overcome difficulty spikes in the beginning say otherwise

### 1/5 — Ads

*2019-06-24, version 1.1.2*

Ads ads and more ads.

Seriously, stop having ads play right in the middle of a wave. I’ve lost count of how many times that when the ad is finished, the wave has failed. I don’t mind reward based ads, or even the occasional ad between waves, but at least pause the game while the ad plays.

Update-  I deleted the app. The ads interrupting game play are just too annoying.

### 2/5 — Fun but adds render unplayable.

*2019-06-17, version 1.1.2*

Started off super fun until adds started interrupting gameplay. Not playing between levels but at random intervals and it pausing the gameplay while the adds are streaming causing level loss.
