Great! Genesis needs games like this. Its hardware should be capable of running all those gold classics of early 80s. We do lack proper Centipede, Millipede, Scramble, Pac Man, Moon Patrol, Aeroboto, Xevious... As for the speech you could add a co processor to the cartridge couldn't you? And prevent nerds from reselling the ROM.
Too bad the author forces me to watch the intro over and over again, with no chance of skipping by hitting a button. Most Genesis games do not do this.
