The game is intriguing, and I like the mechanic of having to redirect the laser to hit the enemies from behind. One thing I find slightly annoying is the path finding. Often times, the enemies get stuck at obstacles and don't walk towards the player. Also, in the end, it can be time consuming to find the last few enemies. With better path finding, this problem should be solved. Another solution would be to have an arrow point to the closest enemies when there are only a few left.
All in all great job, the things I mentioned are merely quality of life ideas
