EDIT: Found the option, was already implemented. Very good - i'm still old, bnut now i can spend as much time as i want!
Why the holy f*ck are there time limits on the boss levels?!
To explain the problem on this: You're starting small in a boss level with a tiny and mostly easy problem you need to solve (of course!). After solving it, the game state enhanced and offers a second puzzle, slightly harder than the puzzle before. This goes on for about 5 to 10 puzzles. Every tiny puzzle has an own time limit. If you connect something right, you gain some time, if you make mistakes, you lose some of your remaining time.
The last one (in the second world) is really hard to solve, because you cannot draw the energy lines as you want. You need to think about it, how to change them to get the puzzle solved. This takes time you simply don't have at that moment.
If you break the limit, you are doomed to make alle the puzzles again, since start of the game.
I found a guide in the steam community, but even with the solution, i don't get the level done, because i don't know how to change the wires to get the two green fields connected above the the lower red one. Again, you cannot disconnect the red ones and you have not much time to think about it.
For smarter People, this might not to be a problem. For old people who needs to decide if they spend their remaining energy for breathing or thinking, it will. I'm one of the last group.
I really wish an option to deactivate it and hope the devs will implement it for old people like me. In my perspective, it is unnessecary, at least for the base game and campaign.
About the stuff i seen until the second boss level: good puzzles, easy rules, good tutorial. Graphic and sound is okay and good enough to concentrate on, what matters: the puzzles. The story seems to be nice, you even have choices about details in the story.
No recommendation for now. Will change my mind if i may think about the levels as long as i need. Thank you
