Cool take on the theme! Really enjoyed it! :D

Like the idea.. You did a good job wit the path.

✔️ I think there is a really cool concept here. Showing the path was also a nice touch, I think it would have been too difficult otherwise.

✔️ The game is also really easy to pick up.

➖ I didn't like how you had to restart from the beginning if you ran out of lives. I could lose all 5 on a single level in a matter of seconds.

Beat the game after a few tries, while it's a solid concept and way more fun than I anticipated, getting sent back all the way to the start is a bit too punishing, especially on the last level where you spend your first few lives just finding out on how the level is even built before you are already sent back to the start and have to play through everything again. It was so fast that I basically just won by getting the mouse stuck in the wall, otherwise I would have had to play through the entire game a dozen more times.

Tl:dr While death in the later levels is too punishing and the game is generally too fast, it's quite a lot of of fun and once all the minor annoyances are ironed out can be a really great game!

I really really liked the concept (I love puzzle games), and having the track visible is super nice, I've never done pathfinding, seems hard!

Sadly, the game is just too fast. I understand it being time sensitive is a core mechanic, but it's just unforgiving. If it let me replay the same level over and over it wouldn't be such a problem, but as it restarts form the beginning, it gets frustrating. I got to the level where it's just empty and there's a button but i didn't know how to push it, and the mouse is just to fast for me to redirect it so early. After a while I started having issues with the box placement, sometimes it worked as drag&drop, sometimes I had to click on it and click again to place it, and that lost me some games. 

I don't want to discourage you, you probably didn't have any feedback until now so it's normal you tuned the speed for yourself. The foundation is solid and I encourage you to keep building on it if you also like the concept.
