arrow keys, particularly up.
Great concept and graphics, but collecting that much sunshine is way too much of a challenge for me.
I peeked at the ending via the source, though. Love it! AND it leaves room open for a sequel!?
if anyone else wants to see the ending without having to collect 50 sunshines in one go, hold down S+O+P while keeping stanley aloft. it's a special challenge for your fingers.
My keyboard won't register all four keys at once, making it extra challenging! But I managed to pull it off.
My time: 115 seconds.
