I must admit, this is the best game I have ever played in my life. What makes this game really amazing is the story and simple but cute characters.

I found "The True Beginning" at my first attempt, thanks to the creator for making good character introduction! At first time I saw Nil, I thought she was a bad guy. But at second time I saw her, she just repeated "Stay", "Stay" and "Stay". I wonder what happened with her and why she has similar to Space. Does she need a help? Then at the third time I lost Space, I got an opportunity to ask Nil what's happened and why she just messing around. Then I realized that I'm the one who messing around and not Nil. Then I decided to reset the timeline again to make Space happy without hurting Nil (but make both of them happy).
What an amazing story!
Suggestions : It would be nice if you make a doll or something hug-able like dolls or anything. The character's simplicity of design (and cuteness) make them possible to be adapted into a doll.
