A thought-provoking platformer with good controls and sound; it suffers from the inability to skip text, which becomes more of a problem with multiple playthroughs.
Supposedly the Golden Astronaut is "hidden on the ending screen," but right and left clicking in Ruffle doesn't show anything (at least on the black screen.) It may or may not work, but until confirmed I will sadly have to assume the medal is unobtainable.
