This was absolutely brilliant in every way. The songs were awesome, and you made them all yourself. The animation/art was simple, but good, and it synched with the music very well. The story is fantastic, and it has a lot of humour. There are a few flaws, such as the skin being so pale you couldn't see the eye whites. But everything has flaws, and there was so much effort put into this, that I think it well-deserves a solid 10. You said "to be continued" at the end. not sure if it actually will be, since it's been 2 years. Although in your authors comments you said this is the conclusion, you also said you're not sure when you'll "get this new one out". Either way, it was a nice cliffhanger.
If I were to rate this on each aspect, I would give the audio a 10, because it's just brilliant. The animation a 9.5, it's simple but works so well, and looks really good in some parts. Story also gets a 9.5, as it's captivating, reasonably original, very funny and had a lot of work put into it, but not quite "10" worthy.
Overall, an excellent job on this.
