It's got zombies.
It's got puking.
Truly, this VN accomplished precisely what it set out to do!
The art is endlessly endearing; despite usually not caring much for zombies, I found myself feeling completely charmed by our big, sad, slow-witted undead protagonist, heheheh~ The medium is used to great effect here as well, particularly with how the backgrounds undulate and change throughout the various scenes in response to Zero's mental shocks.
I also greatly appreciated the sound design! I love a good underspoken ambient soundscape punctuated by the occasional sharper moments, heheh~ As for the writing, I feel it does a great job at fleshing out the main girls despite its brevity, not to mention the potency of the Main Event—it awoke a new fetish that had been heretofore lurking deep within me...
That is to say, you've succeeded in making me worse with this VN.
Stellar work!
