### 4/5 — Good game

*2026-01-12, version 2.0*

But is there any bug with the achievement “inventor”? I have tried countless times and solved more than 15 levels past level 40, but still cannot complete…What is the definition of start points? Are they the mechanisms that are clicked first at the beginning of a level?

### 5/5 — Good game

*2026-01-10, version 2.0*

Great game to play when bored

### 5/5 — Dazzling Fun ;)

*2025-11-24, version 2.0*

Responsive, beautifully-designed puzzles with well thought out difficulty progression. Very polished product!

Has good daily and weekly content to keep you engaged. Great to pass a little time and keep the mind engaged <3

### 5/5 — Beauty & simplicity

*2025-10-31, version 2.0*

I have been using this app daily for a long time and love it.
Today, 1st November 2025, the four daily puzzles were beautiful. Number 4 was the most elegant I have completed in ages and the other 3 were a delight to complete.
Keep up the good work

### 3/5 — The play is good the story terrible and needs a disclaimer to not attempt.

*2025-10-20, version 2.0*

The light bending problem solving it nice to play, the story which is supposed to calm or relieve your focus for a bit, just angers me more as I play. The housewife/mad inventor is creating dangerous products that will no even function, hurt the people using them, or damage the area it works in…what the heck developer?
You replaced a wheel on a bike for shoes…do you know that shoes without proper pressure placement, they scuff the floor.

### 5/5 — Love the idea

*2025-10-08, version 2.0*

Very enjoyable game working with light reflection

### 5/5 — Awesome casual puzzle game

*2025-08-30, version 2.0*

Fun to play if your into games that test your brain.

### 5/5 — a masterpiece

*2025-04-25, version 2.0*

I’m not going to say much except I got addicted to this game and I prefer it over tint. (tint was a bit too hard for a person of my skill level 💀)

### 4/5 — Cannot get past level due to bug

*2025-04-24, version 2.0*

Same complaint as earlier commenter. Im only on ch 1 and I’m not sure why it said I used a hint because I did not use one. I don’t need one. I know how to play the light & mirrors game. It’s easy. Now, despite repeated rounds I still only get 1 star and can’t progress past level 9. After sailing thru 1-8. So, I can’t play the game now. Pretty sure that’s not what you intended. Really disappointed. Please fix this.

### 1/5 — Adios broke. How do I fix it?

*2025-04-16, version 2.0*

No audio comes out when you start the game I’ve tried deleting and reinstalling any other suggestions?
