Okay, I fully played through the game, and I watched the YouTube video that's in the comments. I got all 3 endings, and it was really good. The cover art the creator made is beautiful, and the game itself is so pretty. No tutorial, but honestly, I couldn't care less as it was good to figure out the game on my own. My final score was 31,061.
Also, a little on how to get the endings if anyone else plays this and needs it. Ending one is anything from 0 to 25k points. Ending two is somewhere between 26 to 29k, and 30k+ is the third ending.
