It's hard to tell right now, since there's so much that's unclear about the game. With the mechanics clarified and the game polished, it would be somewhere in the middle.
What small addition could make the game better?
[x] Having the inventory be persistent throughout the game could make it easier to both track purchases at the shops and plant seeds in the field.
Did you experience any issues?
[x] At some places along the edge, the plant still appears to be held in the player's left hand even after clicking to plant it. Maybe it would help if the plant is only visible (enabled) while it is within the field.
Were any of the game mechanics unclear?
[x] When interacting with the shops and inventory interface, the quit button seemed to correspond to the UI instead of the game. Moving the quit button to the start screen only and adding a button in the pause menu to return to the start screen might be a better idea.
[x] The "Plant Seed" button could be changed to something like "Pick Up Seed" to make it clearer that it was a necessary step to start growing the plants.
