Fantastic little game! The platforming is actually unique, and it features just the right amount of levels, always introducing new mechanics at exactly the right time. This is already great, but combined with the absolutely gorgeous minimalist visuals and sound design and music, all of which are engineered to pair with the flow of the gameplay!? Genuinely astounding work. It's small and simple, but every detail is crafted to perfection.
The only actual complaint I have is that the difficulty in the post-game levels is a bit all over the place, and could've used a bit more work. But it's still fine, and is optional, so it's not as bothersome.
Highly recommend!
