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.
