The only word to describe this is masterpiece. Paper Lily is incredibly ambitious and delivers more content than you could imagine in just one chapter. I spent 11 hours playing through every last bit of it and getting all of the "endings". The side quests are so fun, and the alternative ways for moving forward are brilliant. I can't get over how much there is to do - it's so satisfying as someone who likes to click on everything I see.
Compared to the demo, the enemies and settings are scarier in this version, which I love. I liked intentionally letting out the primals to spice things up. The art is simply gorgeous, and the characters are lovely. It was cool to learn about how the characters were developed from the supporter pack. I can't imagine how much time and effort it must take for only two people to make a game of this caliber.
Even though this is just the first chapter, it is definitely one of the best games I've ever played. Highly, highly recommend.
