## What is Critical?

Stop the reactor from going critical by delivering water. Robots are expensive though, so we use cheap expendable personnel instead.

Spend your hard earned cash to unlock permanent upgrades. Invest wisely to make each new run longer than the last.

Tons of upgrades to buy, research to be done, and secrets to uncover. Give it a try!
The longer you can keep the reactor from exploding, the more money you’ll make. Start small and watch your income grow exponentially as you survive longer and longer. Delay the inevitable cataclysm as long as possible and watch your cashflow go through the roof.

### 1/5 — Data gathering

*2026-03-04*

That Firebase list of data is a little crazy. Top of that when you confirm anything you opt out of and go back in to check it re-enables everything. Great game. Bad practice.

### 5/5 — Ver good just needs skill tree

*2025-12-31*

Addicting

### 1/5 — Very stupid

*2025-05-27*

Bad game don’t bother

### 1/5 — Nope

*2025-01-06*

So I don’t usually write reviews but this is one of the few games that I full on wish I could demand a refund from, cause I decided to see about making things easier on myself, buying the ad blocker to make things a bit faster.

Well, it didn’t do much to speed things up, still felt like I was stuck around maybe four minutes, so I decided to look up and saw oh hey, it had codes.

So I thought.

This is why I decided to write a review.

Cause the entire codes thing? Oh here’s a random draw where ten people will get about ten thousand upgrade points, or twenty five of the in-game currency, or you can buy them in game.

I can forgive a small amount of a boost for an ingame code, but a full on lottery? Nah I’ll pass.

### 2/5 — Slow start & Bad font

*2024-12-19*

The start to this game is just way too slow, I can spend 30 minutes just to get less than 100 coins also all the font in this game is quite hard to read and it really just hurts the terrible experience that this game already is.

### 3/5 — Potential but not good yet

*2024-10-10, version 1.08*

Slow & dull progress with a need for near-constant interaction even after buying the automations in the game. Plus you can’t lower their automation nor turn them off - unchecking them does not work. So the game is a dull & partially broken mess. Loads of potential, and does not push in-game purchases, but to make any progress at all you need to play actively and for many hours plus watch loads of ads.

### 1/5 — Scaling is a mess

*2024-07-11*

Seemed like an interesting incremental game. Would have loved if it were just 10 buck on steam and didn’t have a terrible scaling problem at the beginning of the game.

### 3/5 — Because it tries to trick you into a 5 star review

*2023-08-18, version 1.03*

The interface asks you for a star review and when you try to click submit it goes to 5 stars. 

Game is fine otherwise.

### 1/5 — Buggy

*2023-08-12, version 1.03*

I can’t turn on auto play :(. I have tons of whatever icon that is.

### 1/5 — Pretty terrible early game

*2023-08-12*

I played this for an hour or two. I read the tutorial, got 2 managers and upgraded personnel as suggested. No matter what I upgraded I only get 7 coins per round. So upgrades don’t seem to help at all. I played about 20 rounds and without seeing any growth I’m just done. 

Looks like it could’ve been a fun incremental game. Too bad the beginning scaling is so far off.
