The first level was quite fun to find out the solution for, but at first I thought the boxes disappearing on the wrong buttons was a bug, and not intended. After that were only Mazes which were annoying, since the player moves way too slow and it seems like the button was always either to the right or directly next to the middle. I ended up stopping after the 5th or so maze because it was very repetitive and not very fun
But good luck getting the job at Unity
