I really like the minimalism in the visual and music. It's overall very clean and slick.
The also enjopyed very much the gameplay. The mechanic of climbing is I think very original and interesting to play. Like others, I was stuck in the last level because I didn't fully understand how stacked blocks works but in the end I figured it out and that was satisfying (a bit frustrating too)
But overall a top notch experience. I really enjoyed it.
