I have played the game a few times. The last time I've played it, it has not sped up, I repeat not sped up, but envolved in the sense of interacting with the graphics of the game, the playability. Like, it has been unlocked for a few secs.
The killing and moving in the game (well known tough Alien Breed) which was tough, for a few secs remained very handleable and much, much more fun. How about it? Guess that all the Classic Amiga games got unlock and you could like play them all again but unlocked on your old, previous, new classics configs.
I'd bet on this one, AFAIC.
