Beautiful game.
The soundtrack deserves a special mention, because it manages to transmit the sad, melancholic feelings of traversing a ruined kingdom.
The story is nothing new 'cause games like Hollow Knight use the same motif, but despite of that Ender Lilies manages to get an identity of its own. Also, the hidden side stories add a lot to the main plot.
Gorgeous art style and animations, and stunning, somewhat nostalgic atmosphere and level design.
