Sounds like it might be a bit late for suggestions, but I think it an achievement for the hidden bird Easter egg in Sky High Zone would be cool. That is assuming the Easter egg is not exclusive to the Master System version of course.

My progress has been a bit on the slower side due to real life commitments and prioritizing my admin duties. Rest assured I have not forgotten about this set - I just need to set aside some time to dedicate to finishing things up.

@ It's definitely in the works!

Thanks Looking forwarding to this set. I've played a lot of Sonic 1 and Chaos, but haven't gone back to this one as much over the years so this will be a good excuse to revisit it. Mind you the last time I played the Game Gear version I got stuck on the first boss thanks to the screen crunch!

I'm renewing my WIP on this set a bit early, since I will be away for the next couple of weeks, and my current reservation is set to expire in that time.

All that is left to be done is for me to test the remainder of the achievements. I will take the final steps to getting this set live once I am back from my time off.
