### 5/5 — Cleanest, Well Made, Mobile Game Ever

*2023-10-29*

This game has no bugs, is offline, no ads. But most importantly, its fun. Genuinely fun

### 5/5 — YOOOO

*2022-09-14*

this is good, the fire boss hates my very existence though

### 5/5 — Mobile Game Perfection

*2021-05-15*

Like a mobile rougelike that reminds me of many beautiful steam games like Nowhere Patrol. The autoshoot feature works amazingly with such a tight space for gameplay the controls take time to get used to but it is well worth learning how to play. I aspire to make a great game like this myself one day. Probably top 20 mobile games ever made and i mean that wholeheartedly. Also the monetization is great for a mobile game. Overall zero flaws so far. 5/5 game.

### 4/5 — Pretty good.

*2020-02-17, version 0.7.5*

I like this game.    Takes a couple minutes to master the controls.    Nice shooting system. 

It’s fun so i like it.

### 5/5 — The best

 This iz a very fun Mobile Videogame & your chip tune music iz most excellent. Thankz for your heArtwork in this amazing & Funtaztic creation of yours.

### 5/5 — Super fun

*2020-02-02, version 0.7.5*

Great little game. Easy to pick up and play, but surprisingly nuanced.

### 5/5 — De la fraîcheur dans le jeu mobile

*2020-01-29, version 0.7.5*

Ce jeu nous offre beaucoup dans la personnalisation et le style de jeu. Les combats de boss sont selon moi les plus intéressants et chaque stages, bien que petits, sont bien pensés. Rien a dire à part peut être les bonus un peu répétitif mais sinon coup de cœur.

### 5/5 — Finally, a mobile game I didn’t delete after a few minutes!

*2020-01-15*

A simple arcade style platformer and graphics with bullet hell type gameplay, but one thing that gets on my nerves is the shooting sensor— sometimes my character shoots at something that’s behind a wall or something or even misses sometimes. There were many where there’s an enemy attacking me but I cannot attack it... being able to manually aim is quite essential to a shooting kind of game. Maybe add a joystick to shoot with? Other than that, this is a fun retro game worth downloading, and deserves more praise than some of the front page apps.

### 5/5 — This Game Is Amazing!

*2020-01-15*

Everyone who is looking through the App Store has to download this game!  It’s very fun!
