Cool game, great concept, nice atmosphere, painfully unresponsive controls :( After finally figuring out level 10, it took me about 15 tries to take the dark orb out and replace it with the light one because the character would just refuse to pick up/drop anything at seemingly random times. When I finally made it to the door, I walked to it, pressed the up arrow 4 times, held it, and slid off the ground's edge.
Upgrade abilities:
Break through those caution-tape boulder things
Be able to climb up the edge of a platform from further away from the top
Warnings of hanging walls and boulders
Finish the game. Play again using "New Game+", complete quests for duplicates of all the weapon-wagons you already have. Repeat until you have 100 wagons and defeat Wooly in a second.
I got to the boss by keeping my finger on the right arrow and mashing the up arrow... Then when I reached the boss, I dodged his "attacks" until he stopped moving and turning pink. I jumped on his head with 5 lives and was immediately sent to the "game over" screen. 2/5
