Interesting idea for a game! Nice graphics! However, the location in the garden, where you can find various treasures - it lags a lot for me, I don't know if this is a common problem, but I tried it in Chrome and Mozilla without laptop charger.
I planted a full garden, I was getting about 20 gold per day - not bad for me, but for 1000 gold, I think I can't do without treasures :).
