Yes, it sounds like SQ3
I've found the Easter Egg, and I've reached a maximum of 315 points! I wish that I could have a chance to play with the cockpit, like in the original game... Maybe the IQ team will make a surprise in version 2.1 ;)
Hahah, probably not. I threw the SQ3 Easter Egg in on my own in my spare time, and still didn't have time to finish up everything I wanted to about it. I'll leave making SQ3 up to another team, for sure. Glad you found everything.
