Heyo, I couldnt get past level 4 but I was nonetheless excited to try it a few more times which is a good sign! I especially like how the movement and attracting of enemies works. It gives you room for a lot interesting puzzle layouts and designs and furthermore there is an intuitive tutorialisation process (the actions more than the words that you present) that you're moving the player through. I do think the enemies move too quickly and things feels a bit crowded but if that's what you were going for then good job. If that is the case I think its worth thinking a bit more about what that means for your gameplay cause right now its dynamic is somewhere between being really fast and slow and methodical.
Beyond that I would also say let me retry a level from where I died and make sure your description is more accurate towards the experience you're reeling players in with. Good job!
