## Most critical reviews (4 lowest-rated)

### 1/5 — Not functioning

*2025-08-06*

I’ve bought every addon to the game and now I can’t buy upgrades for the marbles. I’ve been playing for a few days and the ad based upgrades after buying the no ads don’t work for the full time and just disappear in the middle. I also requested a refund as the game is unplayable now as I cannot upgrade after prestiging.

### 1/5 — Better factory games available

*2025-08-01*

Progress stagnates pretty quickly and the marbles are hard to tap and kinda greedy

### 3/5 — There is a problem

*2025-04-28*

I love the game the marbles customization ops and cards BUT there seems to be a data retention problem because the last time I played I had 1.5B saving up for the final track piece I come back today I see only 10M after watching ad after ad I still haven’t gotten back what I lost please fix this issue ASAP

### 5/5 — Game

*2025-07-17*

Good game but it says it’s idle but it’s not you don’t get rewards why you aren’t playing
