For anybody here lamenting about Flash being dead on popular web browsers:
You should use Basilisk with embedded Flash support! (Until the NG Player will ever be fixed...)
For the game:
One of the Matt's classics - the music is like heaven for ears (thnx Phymna)
Each enemy has its bullet pattern!
The said bullets will kill you quickly if not careful!
Each character - even No-Legs - has its own ups and downs...
Basically - the great game!
Also this game probably introduced us the character appearing in EBF4... (spoilers!)
