I like the idea and execution. Who doesn't want to become an NPC with a pet rat who lost his pants down the river. The writing is well done, with the art and music being consistent with the whole setting.
The main issue I have is that there is no way of knowing how well I've done. Many of the choices would be memorable for me, so it's hard to tell if I should go for a funny or helpful one. Having the player come back, being able to gain feedback by viewing from some kind of forum, or simply just having a number go up or down would be useful.
Great job on the game and hope to see you in the sequel!
