VNs by their nature are mountains of text that end up with the odd typo or error every now and then, or inconsistencies, or things that get lost in translation. I think a thread to list them would be of some help to patch them at some point.

Use spoiler tags when you feel they are appropriate.

• Youichi brings up the unusuality of Ginga's name. I think the text should elaborate that his name, 銀河, means "Galaxy".
  
• When you pick the option to calm Asuka down when she first sees Aries, a line says "Accordhing" instead of "According"
  
• When Aqua visits Youichi's house for the first time, there's an erroneous @ after she spells out "Oniichan", same when Aries says "Sis" a few times. I'm going to assume that this was meant to be a ～ or a ♡. This might crop up at other points due to being a font error.
  
• In the Space Club's room, the second mention of the term "OOParts" is mispelled as OOPAarts.

Also an engine issue; the choices seem to pop up extremely quickly, meaning it's easy to accidently click them if you click-read. An option to disable the automatic movement of the mouse would remedy this or a cooldown before they're clickable.
