A calm, pleasant, and engaging game. Great work — I played it to the end. But I’d say it lacks a bit of balance =) (not theme "balance" , but in-game "balance)) and some variety, especially in the second half.
Now, some details:
Upgrading the number of moves at start - this is the way. At the start, you spend all your early days upgrading moves. Once you have 15, you start upgrading Intelligence (5) and begin clearing the garden. The next day: more Intelligence (10) + a bit more gardening. Then Strength (5) + plant a tree (5) + garden work. Then Strength (10) + plant a tree (5). After that, every day is just planting trees and clearing the garden if you have HP.
And now the most important part: Armor is very expensive. Aside from the gloves (and maybe the boots), everything else is too costly. You can finish the game much faster if you don’t buy it.
Once the garden is fully planted, you just skip days until your HP is restored (I would’ve liked an option to skip all moves for faster recovery).
After healing up, clear the garden until you find the key.
Once you’ve found the key — and if you haven’t already won — you can basically just keep skipping days. The garden covers all expenses. Though of course, it’s easiest to skip days while healing, then go back to the garden. Repeat until the end.
