Simple and with a chill vibe, had a pretty good time with the game and it got me in the mood to replay Super Mario Galaxy again!
Only hiccup I came across was the camera getting stuck in place when reaching the "above is like below" planet, going back to the central area fixed it but on my first attempt I walked away and got soft locked so I had to restart from the beginning.
Also, you can jump over the edges of the starting area and get stuck in the empty part of the planet, took a bunch of jumping around before I was able to make it back. I think unlocking the framerate helped with that as jumping and camera speed seem to be affected by it?
