The Best.
Cuboy is definitely the best work of flash I have ever seen. It is excellent on every aspect. Graphically, it may not be so full of detail, yet it is truly beautifully designed. Musically, it is filled with funny little sounds and well-crafted songs. Scriptically (?) it is very well written. The whole thing is just brilliant.
It's too bad this and Cuboy 2 are the only two cuboy movies. I'd be delighted to see more, if possible.
