The paper-cutout art style is really cool, the ship, the little alien drawings, they're all super charming. And the way the galaxy is presented all looks gorgeous. I also really like the contrast of the hand-drawn elements with the 3D planets; they look a bit like clay, which gives the whole thing a weird-but-cozy vibe and it fits the theme perfectly.
Flying around feels smooth, and just hopping planet to planet to meet whatever bizarre creature shows up next is oddly relaxing. The sound effects and subtle music do a lot to sell that quietly drifting in space atmosphere too. And honestly, these planets absolutely nail "Strange Places".
