### 1/5 — Garbage

*2026-08-21*

Trash re-skin of countless other games that push a million microtransactions don’t waste your time

### 3/5 — Fun game, but….

*2026-08-17*

First off, v engrossing and fun. After a couple of months though, a few niggles become frustrating. The RNG means ads are unfortunately a big part of this, in order to get a decent build for a level - and they are all particularly long ads (1min plus) that require active engagement - you can’t just let the ad play out. Second - binary star, the other AI player is always super-weak, so there is a big lack of balance. Held up on the same level (Binary 20) for 3/4 of the 2 months I’ve been playing…  Fix these niggles and the game would be fabulous!

### 1/5 — Typical pay to play

*2026-08-15, version 0.1.72*

Beautiful graphics and loads of fun, till you hit the paywall at level 5 within an hour.  You can grind for hours and make slow progress but you can feel the need to spend money right away.  Deleted and walked away.

### 1/5 — 楽しくない。楽しいのは最初だけのゲーム。

*2026-08-12*

他にも似たようなゲームがありすぎてパクリかと思うくらいです。
15面から非常に敵が多くなり硬くなる。
何が楽しいの？と運営に言いたい。
課金は他の方も言っている通りに高すぎる。
見た目は違うが、ギャラクシー、EDENなどと一緒。ほぼ配布も似たり寄ったり。遊び方が違うだけ。遊ぶのはやめた方がいい。時間の無駄です。

### 1/5 — 我发现剧本都是安排好的 他想你赢就赢想你输就输

*2026-08-10, version 0.1.72*

举个很简单的例子 只要你很久没有打开，你一定是赢的 你经常玩就一定输 结局都是安排好了的

### 2/5 — Please add Russian language

*2026-08-09*

Russian language is needed

### 3/5 — So lala

*2026-08-09*

Nettes Spiel, dass andauernd crasht und eine unterirdische Übersetzung hat

### 3/5 — Crazy Adds!

*2026-08-09, version 0.1.72*

If it weren’t for all the Adds this would be a hit 😐😠😭

### 5/5 — !!!

*2026-08-07*

The game is just amazing (out of this world). Please add the Russian language.

### 5/5 — Planet Defenses: Space TD Games.,

*2026-08-07, version 0.1.72*

Needs better shields around the planet that holds up better to repeated attacks on the planet. Also, needs better and more powerful weapons to fight with to defend the planet. Needs newer weapons to defend and protect the planet from repeated attacks.
