I quite like this game. It's simple in controls and premise, but it explores the potential of it well. I do feel like the door puzzle on Level 2 is rather complex, and asks the player to have some deep understanding of the game's controls and mechanics to complete it, when they haven't had the chance yet (though that might just be me being bad at the game), and I feel like rewinding all the way back to the start, while thematically appropriate, might lead to some players feeling like they're backtracking. But overall, the mechanics, design, and visual style of the game are pretty nice.
