Cute and fun little game! The presentation is overall very charming and the chaotic nature of juggling zombie killing with crop-growing was very amusing and creative. I liked the little extra strategy of saving enough blood to grow the bullet plants to get ammo for the shotgun in a pinch: would've loved to see more strategy elements like that pop-up as the game went on.
While it was nice, there were definitely some annoyances that got in the way of me enjoying the game. For one, getting used to aiming the water bucket and the auto-aiming system was very difficult at first, and in fact I still have some awkward interactions with it even now after practice. Two, I come from Harvest Moon sensibilities where sickle-ing your plants means destroying them, not harvesting them, so I was a bit confused at how to progress and why my character kept trying to auto-target the plants since I thought they were destroying them friendly-fire style at first. Finally, it was annoying how you could wastefully pick up more blood than you need to, and also pour more than needed as well.
All in all, I had a pretty good time with the game despite some minor gripes, though I'll admit it got monotonous rather quickly: with no major gameplay innovation to spice things up as the days went on, the story intermissions were not enough to keep my interest alone. Still, good while it lasted.
