Great game! Two days of classic old school snake-y goodness during downtime at work. (An occasionally at the cost of productivity.) Hard badge was appropriately hard, but not ridiculous. (As was the game!) I liked the difficulty curve. When I started I kind of wrote off getting the hard badge. But the learning curve is such that you're ready for the challenge by the end. Trouser, Krait, Rat, Puff, and Python were my Dev+ wins to progress to the end - seemed like the easiest ones to achieve to me.
