This might be one of my favorite games on Kongregate! Great job, you've absolutely outdone yourself. It would be a great addition for a sequel to have a bit more progression aspects, and even more loot. The loots are my favorite part of the game, so if there's ever a sequel, make sure to double or even triple the loot! Also, maybe cut down on the repetition by adding more sets of scenery and obstacles (whatever you call those defined chunks of terrain). The game is a slightly unrefined stroke of genius, and the only major improvement I can see for a sequel would be to make it absolutely massive!
