Good game

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?

Good game

Great game to play when bored

Dazzling Fun ;)

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

Beauty & simplicity

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

The play is good the story terrible and needs a disclaimer to not attempt.

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.

Love the idea

Very enjoyable game working with light reflection

Awesome casual puzzle game

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

a masterpiece

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 💀)

Cannot get past level due to bug

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.

Adios broke. How do I fix it?

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

Enjoyable

It’s quite fun, not overly complex so far

Exciting

Love these puzzles… ty for this game… keeps my mind sharp and love the challenges…

Fun and challenging

Great game with lots of thoughtful touches. I love the daily challenges and weekly mazes and having been taking my time with the main levels because it seems like no updates are coming and I don’t want the game to end. One bug I’ve noticed on the main levels is that the game only records your score for the first successful attempt. So if you only get 2 stars, you can redo the level and get 3 stars but next time you open the game, it still shows 2 stars for that level. This is frustrating because you needs certain number of stars to unlock various features. If this was fixed I’d give the game ⭐️⭐️⭐️⭐️⭐️. Another note for the designers: it’s unclear what most of the buttons on the box screen do. You can move forward and back among the images but then there’s line 3 more buttons of uncertain use. I’ve pushed them all and they don’t seem to do anything and there’s no explanation anywhere of their purpose.

Response from developer

Hi, thank you for reporting this. We will look into it!

Plz update this game I love! 🙏

PLEEEEEEZE UPDATE!! 🙏🙏🙏
I certainly enjoy the daily challenges, but I’m dying for more levels! I’ve played all 265 levels 4 or 5 x’s.
Is there a similar game out there?!

Needs improvement

The puzzles are fun and every one is different making it continually challenging. However, the storytelling is awful and looking at her inventions close up in 3D (every 180-ish puzzles) after already seeing them in the pictures/narration is lame. One suggestion: show the invention first, then slowly build up to what it is, leaving people to try to figure it out with each clue they earn through completing puzzles and the resulting pictures/storytelling (obviously the storytelling would have to be redone to be more cryptic for this to work). Or put some kind of murder mystery behind it, giving clues every 180-ish puzzles? Cheers for the fun puzzles though.

So good

So good

A work of art rather than a beautiful game.

The aesthetics are just amazing, although the puzzles could be harder, I’m overall impressed by lumen.

Repetitive, too easy

Whilst Lumen looks nice, with flashy graphics and visual effects, it is simply boring. Every level is the same, by which I mean you simply have to rotate mirrors on a board until you light things up. It's too easy, there's no sense of progression, and the faux steampunk back story is frankly embarrassing. And it eats more than half a gigabyte of your storage.
