WoodMan is....not bad.
Woodman simply getting one-shot after his dramatic intros wasn't funny the first time and shouldn't have been repeated again as a joke.
That aside, though, it did have its moments. The opening menu looked really good and the jokes that worked were actually funny. "...with my powerful leaf attack! Woosh!" and Wily's response. Those were entertaining.
Visually, it looked good. I'm really glad to see people not giving up on sprite-based Flash and classic MegaMan is much more refreshing compared to the billion Sonic or Mario flashes. WoodMan rocking out to the credits especially looked nice. So as far as presentation goes this wins.
The humor is just a bit hit-or-miss. I do hope you do more, though. This is a lot better than most of the MegaMan flash content on Newgrounds currently.
