Very interesting game idea! Kind action-puzzle. But I found it a bit too hard, given that both energy limitations and enemies move around - I think it would be better to have some implications, like having a bouncing line to aim. It took me too many tries to finish just the second level.
One minor suggestion for text in the beginning - it would be cool if the first click didn't click the message but displayed it whole, like in many other games. I ended up skipping some text not because I wanted to skip but because it was too slow, and I wanted to see the whole text at once. Also I think it is a bad idea to make all the lines move up when another line is added - it is a bit painful to the eyes.
And cudos for Godot :)
