I love the visuals and the minimalist architecture (probably inspired by Monument Valley?). Gameplay-wise, it's pretty simple and effective, but a few mechanics aren't super clear especially the copy mechanic with lever. Same for the climbing, which could have used better environement feedback so you know you can grab the walls. On the audio side, the music is cool, but I would've liked more variation in the SFX for movement and dialogue, as they get a bit repetitive and annoying over time.
Great job!
