The project has handled in two phases since the intention was to raise the necessary funds through Kickstarter. The main character, Mai was designed in phase one along with some backgrounds and CGs for the demo.
These are some of the choice quotations from reviews regarding the art for the game:
"The sprite art for Mai is lovely. Soft colors and expressions fit her quiet demeanor. I especially like her smile. The single CG in the demo matches the art of the sprite and backgrounds very well. All of the art is consistent, and I praise Space Penguin’s work on the project for that consistency. The background art really captures the feeling of the gloomy weather and the dreary world, especially the abandoned battle field." - Mystery Corgi, ADVaNCE
"The first of those reasons is the striking visuals. The artwork for the game is being produced by Hui Tian (Space Penguin) of Collateral Damage Studios. Beautiful scenery, unique characters and captivating CG art are showcased on the campaign page." - KRISWB, thisisxbox
