Welcome to the forum! This is an interesting design for a first level. Although you took some care to avoid winning with the free draggables, I was still able to win with a zapper... Spoiler I just had to place the satellite in the zapper's way, the zapper climbed it and I dragged it so he'd reach the win... The concept is interesting and requires some good timing, but the solution is almost too quick or too easy depending on how you play it. Now let's see your other levels .
@Chuckthulhu Thank you for playing and a comment I tried to reappear the situation you told. But,I couldn't make it because of my ignorance
