There's something about a nice isometric art style that makes me keep coming back. I love the little details around the plants as they grow over time. The watering animation, while nice, was a tad long. I wish it was about half as long, but not a big deal (why I said keep the double watering in as a "feature" in another reply).
The first time I met the thing in the drain was so great. Sadly, I was getting around the end of the 2nd spring and had it alt tabbed for a couple min and when I returned, it was at the "Summary" screen, but it wouldn't let me continue, so I had to call it quits.
All said, that was pretty cool. Curious though, does something happen once you feed it enough peppers and potatoes? I couldn't tell if there was a progression related to the creature.
