Very good presentation and nice minimalistic graphics! The first few levels are very interesting. The gradual addition of new mechanics and pieces is on point, and the doors with lore were a great way to bump the challenge for completionists.
But the later levels became annoying as it was no longer about puzzle solving but about timing, time of placement (spinning platforms), and mouse agility. I like puzzle and strategy games, but for me (and I believe for most) it's a put-off when puzzles get mixed with agility/skill, meaning when I'm no longer sure if I have to think or train my muscle memory.
