### 5/5 — Upgrades

*2025-03-01*

I think you should add a percentage upgrade of your bullets being able to penetrate through the enemies and also maybe a multi colored hyper gun than can be bought. Thank you and hope to see new upgrades.

### 1/5 — Beautiful but not fun

*2019-10-20*

App started out fun but upgrading triggers increased difficulty which in turn makes it impossible to accumulate the gems needed to upgrade.

I give up.  You win.

Deleted.

I win!

### 4/5 — Good time killer

*2019-09-23*

If you enjoy the top-down bullet hell type game this is fairly well done. Not enough actual bullet hell for me but that’s just my opinion. 

Quirks: occasional bug where the screen goes washed out or darkened until something else major happens (like a boss). Another quirk appears to be when completing a mission ... not actually getting any compensation for it. Just got 7 done and earned ZERO crystals for the run or mission completion.

All in all enjoyable. Grinding is a part of the genre so expect it.

### 5/5 — OMG!!!!

*2019-09-10*

GORGEOUS!! AMAZING!! 194Who? This puts everything else in this genre to shame!!

### 5/5 — Great game

*2019-02-14*

Fun and addictive bullet-hell game with unobtrusive IAP.  The prices on upgrades could be a *little* less grindy but they’re not bad enough to detract from the positives

Great controls, graphics, and sound- the underwater/neon aesthetic is unique

There is a bug that occasionally causes the screen flashes to get stuck on the screen, making it hard to see, but it doesn’t happen too often, and it gets unstuck when you either get hit by an enemy or reach a boss.

The relic-crafting is where the addition comes in- you want to be earning relic pieces so you can craft new relics, which give you buffs in various areas.  I do think the shockwave relics are a little overpowered as the shockwave (which is triggered every 3 seconds on some relics) knocks away enemies, bullets, fire, meteors, you name it. There’s not much reason to use anything other than shockwave 

All in all, great game!  Would like to see an IAP expansion or sequel!

### 3/5 — Please update!!!

*2017-10-08*

I have an older version of this app.... I won it a couple years ago by finding all the correct differences between two pictures. 

I can now no longer play since iOS 11 came out. 

Would like to play again. 

Please update
