I really enjoyed your game..
I was looking for a game just like this, a nice casual play with some funny humor.
As you stated, this was just a game to practice your flash skills, so viewing it in that light through the game made some of the less-awesome parts of it more understandable. All in all this is a pretty fun little game, I probably won't play through it again because I think I've ridden all the rides on this one.
I would like to see more stuff to do in your next game, going to the right and pressing up over and over wasn't as enthralling by the 20th room or so, but by then I was sucked into your thought process about souls and had even forgot it was a game.
Ya did a fairly good job all in all, but next time increase the fun level by adding in more things for the player to interact with. You're awesome tho, Like Mr. Takayashi.
