垃圾遊戲

### 4/5 — Good but...

*2022-02-22, version 1.7.1*

I love this game so much but there’s some things that I think you should add the first thing is that you really should get more red gems when you rebirth and you should make it so you can customize your canon with different abilities and skins and stuff like that and possibly make a multiplayer version where you can work with a person to complete all the upgrades plzz :)

### 5/5 — Cool :)

*2022-01-08, version 1.7.1*

I just started playing this game a few weeks ago and I like it! I like most features of game and I would wish and hope that the developers would update the game more with new items and new stuff in the lab. TLDR: Good game, hope for more updates. -Nux

### 5/5 — Offline issue

*2019-12-14, version 1.6.5*

Ok fist I wanna say I love this game, I’ve been playing for a couple days and I love it. The only issue I have is the offline thing. I come back after a day and I didn’t even get past a wave. Normally I could get past 5 in 2 minutes. I think if you could update the offline problem this game would be AMAZING, not that it already isn’t I’m just saying it would be wayyyyyyy better then before
