Hmm......well....i'll just use one game over screen....it'll be easier. I was gonna have three power towers (I dunno what their called.....those things that cables come out of....it's all electric and stuff :P) have a lightning animation on each tower, and if you touch the tower, the game over screen would be "You got electricuted" or something similar. Ahh well, it's fine.
Would it not be possible to set the game over screen to just Game Over, and have it so that when you touch one of the pylons it sets off an event - game over music and a picture fades in saying "You got Electrocuted!"....which then fades into the Game over bit...??
That's pretty much the idea of having a separate map that calculates all that (instead of it being in a Common Event slot), though instead of a picture I figured on a background - no worries about positioning and all that. Also, if you wanted to, you could have random characters acting out what just happened (your character getting zapped and turning to dust, or something) in the foreground.
