Thanks for playing, and thanks for the detailed report! If you don't mind sharing, what browser were you playing on?
The watering bug may be the withering mechanic if the plants were planted and then the day was immediately ended. Withering stacks up to 5 times for each unwatered day and each watered day removes 1 stack. As long as a plant has a stack of withering it grows at a quarter speed if watered. When I do an art pass, I'll try to make it more visually clear with some cracks on the ground, and maybe add a way to inspect plants.
The time progression is kind of weird. The way it's supposed to work is that it ticks down until the results screen, then ticks back up once you've entered endless play. When I do an art pass, I'll make it more obvious as to which phase of the game you're in
You are correct in that the land placement should be along the axis of the cell you're currently standing on. Possibly there's a bug effecting these three mechanics, I'll keep an eye out for it. Thanks for reporting them!
The lands being the same untilled wasn't a really a planned feature, but to save time in art assets. After playing it alot in testing it does seem like an uninteresting mechanic overall. When I get to doing an art pass, i'll add in sprites to make it subtly apparent that they are different lands. Originally the normal untilled lands were planned to have been covered with leaves, so I'll make a play around with what kind of sprites I can make to make them look different.
