Double Action Blaster Guys by NovaSquirrel is a single player action game but also allows two simultaneous players. DABG for the Nintendo Entertainment System / Famicom is a sequel to “Forehead Block Guy“.



Since the first revision there’s been several bugfixes and changes:

•“Extra stuff” menu on the title screen was removed and the level editor and credits were just moved to the main menu instead
•If the pre-level screen with the objective is skipped with Start, the game no longer starts the level with the game paused and will wait for you to let go of Start
•Credits screen now has website URLs on it
•All unofficial/illegal opcodes are replaced with official ones for better compatibility with emulators that don’t support them
•Fixed a bug where testing a level in the level editor after beating the game would just bring you back to the title
•Fixed a bug where enemies can’t climb over blocks from the right
