Love the art! Some bug reports though during testing, I can't choose an option while messaging the boys (I chose Sieran at the time), so I was stuck there can't do anything, and when in the settings the return button doesn't work but pressing escape repeatedly helped.
Also due to the many boys on screen, I didn't know who was talking at the beginning, too many names in such a short time, and I didn't notice their expression change since it was overcrowded which is a shame. Transitions were very off-putting and the music had weird pacing in my opinion, but I do like the music where we first met the shinigamis.
Also at one point the game just freezes so as pretty as it was I couldn't really enjoy the demo.
Good luck though as I'm sure your kickstarter will follow through the art alone is a good enough reason. I hope you can fix the overall mechanics though as it was really buggy.
