HAHAHAHAHAHAHAAHA YES. YEEEEES xD.
That was really enjoyable, nice idea =p ! I'm not a fan of using 1, 2, 3 to switch "tools", because I have to let go of the direction everytime I want to change (which happens a lot), and I would have loved a bigger watering can, but apart from that, that was really good ^^ !
Oh, and you're the very first game I tested that is able to manage other keyboard layouts than QWERTY, so bonus points for you =p !
