I don't remember the exact level number now, I finally beat it with more than a little luck and a lot of retries. I think it was the .. 3rd one maybe.. with aliens. It was the one with a single alien in the bottom-left corner and a small group of them in the upper right.
The one in the bottom left frequently spawned and stood still right in one of the forks required to navigate around the corner properly, and the ones in the top right spawned on paths that never left the item uncovered.
That's about what I figured the enemy "tactics" were. I'd noticed that each restart they were different, but that they had a pattern for each iteration that was pretty quick to spot. So I guess the one specific feedback I'd have on that approach is that if you're generating the paths randomly, without accounting for how the paths might interact with paths of other enemies, the "Macguffins", and bottlenecks it's possible for a player to just get very unlucky, which makes the game feel a bit unfair.
Some things, like figuring out how to dash around the homing aliens properly, feel pretty rewarding though.
