This is a very interesting game! You got quite a unique mechanic, and also managed to implement it quite well. The only downside is that the game plays kinda slow, and while I understand that having a lot of copies is problematic, having only two makes the game sluggish as well (cause once a copy disappears you have to redo it, which is anti fun). You don't have a lot of sound or music, but the sound that you do have is nice, useful, and fits the game. The bounding boxes of the lasers could be a bit more lenient, since you use (I guess?) rectangle to rectangle collision which makes it hard because a casual player (like me) expects circle to rectangle collision, causing a lot of unexpected deaths. All in all a unique idea implemented in a pretty ok way.

Thank you for your useful comment! You are right with the bounding areas. I was running out of time to implement it;) and if I continue developing it, I will implement better bounding areas first.
The count of instances ("lives") was a tricky decision, because I didnt want to make it too easy. On the other hand I didnt want to show the Game Over screen after three deaths (as I planed first), because this was too hard.

Like bobismijnnaam said the movement is a little bit slow and the disappearing of copies sometimes is frustrating. But I like the concept and the graphics. Well done!
