### 5/5 — Fun

*2023-01-08, version 2.4.2*

Works great with apple pencil

### 5/5 — Love and pain

*2022-04-25, version 2.4.0*

I love playing h thx is game but when I started I got a big headache for no reason I played until I died and left what I had what’s hallucinations of the game but still fun game to play!!?!?!!!!!

### 5/5 — Correction needed

*2020-09-01, version 2.3.4*

To game developer: in your description of this game you’ve chosen to use “challenge your reflexes” as a descriptor; however, that’s actually incorrect to say. Reflexes: are an involuntary response the body uses to avoid danger (hand + hot metal = burn...) receptors are triggered which send signals via a sensory neuron to your spinal cord and passed on to a motor neuron which triggers a muscle or gland to be stimulated. By bypassing the brain, signals being sent through the body are sent and received far quicker. The brain takes time to process and determine a response/outcome. 

What you’re looking for is: reaction time. Reaction time is a conscious decision. They are slower than reflexes, but unlike reflexes, reaction times can be improved with practice. *to a certain extent, within reason.

A more suitable line would be:
       Test your awareness and reaction time. 

Probably wouldn’t hurt to include that repeated play can significantly improve skill. Awareness is linked with reaction time: they aren’t the same, but they can be improved.

### 5/5 — Very good game

*2020-06-21, version 2.3.4*

Very good game

### 5/5 — Good

*2020-03-19, version 2.3.4*

Hard game but fun. NO ADS

### 5/5 — Absolutely bangin

*2020-02-17, version 2.3.4*

Yeah what he said

### 4/5 — great game but glitch

*2019-11-27, version 2.3.3*

I LOVE this game, I currently am number 1 on the duo record list but I am trying to beat Zakku on normal mode now, while playing normal mode I emcountered a glitch with the plasma tracker, A certain part of the circle, around the top a little to the left, the plasma tracker will just keep shooting there and the bullets/ shots dont disappear. Because of this if there is a asteroid on top and you try shooting it you can’t, it will just lock on to the glitched location where the rest are stuck, I have only encountered this twice and it has been in the same or close to same spot each time making me die once but I was only at 164 so it wasn’t that big if a deal. I will rate this 5 star when it is fixed but I’ll leave it at 4 star for now.

### 5/5 — This is really fun to play!

*2019-10-28, version 2.3.3*

It makes me calm down when I’m mad at somebody and also... GREAT WORK ON THE GAME! sorry caps 😂

### 5/5 — Awesome game!

*2019-09-11, version 2.3.0*

Very well made game. Challenging, but fun. Hope to see more Big Frost games in the future.

### 4/5 — Suggestion + buff Machine Pulse or nerf Photon Beam

*2019-03-14, version 2.1.1*

How about a leaderboard for scores before medal bonuses are applied, because it just seems a bit unfair that if two players destroy the same amount of asteroids, the player with more medals scores more and is therefore higher up on the leaderboard. Also, Photon Beam is obviously better than Machine Pulse.
