Had the same tiling issue as UltDev, it seems one of your tilled soil tiles is set incorrectly so it just shows as transparent. Some UI elements would also not show up, so I'd have no idea how much I was watering my plants for.

On the gameplay side, the controls are really bad. Whether it's trying to select a specific item or trying to select a specific tile, the game fights you over it. Honestly I'd recommend against the old Harvest Moon one-by-one approach to items and tiles. Rune Factory does it much better by allowing you to till/water 3x3s at once or allowing you to hold the pick-up button to collect all nearby items of the same type.

Sometimes when i use the hoe on the dirt it creates a hole in the ground but then i hoe right next to it and that fixes it. I wish I could give more advice but these kinds of games aren't really my specialty.
