I can't believe I actually caught this. The first time I saw it, I thought I was going nuts... So here we have the Space Invaders Extreme (DS) title screen. Once you hit Start... ...you have a few options to choose from. One of these is "Exit", which takes you back to the title screen. Now, once you select the "Exit" option, the box containing the "Exit" text wipes off the screen rather quickly, BUT if you look closely... ...you'll catch a glimpse of Mr. ESC! Mr. ESC is from one of Taito's other series, Exit. Exit DS was also released in Japan at the beginning of the year. It's pretty cool to see Taito play around with their franchises like this. I'm also a super-dork when it comes to little Easter Egg and reference type stuff... Wonder if there are any other references littered throughout the game, or if the PSP version has this as well...?
