Now this is right up my alley. Love the replicating mechanic you've got going here. It's super simple, yet affords a bunch of interesting design opportunities!
For feedback, I'd say tighten up that difficulty curve. While the first level is cool, I'd say an easier layout that requires only 1 or 2 replications would be a better fit for teaching new players the game! You can ramp up the challenge from there, since the levels you got rn are all real good.
