For a first timer on godot, I'd say this is very original! Interesting and unique mechanic, has potential for a cool puzzle game. Like others said, the enemies' movement weren't predictable enough, they move too fast and in weird patterns, so when I actually managed to get past the levels it felt more like luck than a satisfying victory
I liked that you put the effort into sound effects. Music was a bit repetitive tho.
Good job! Do feel proud!
