Just another SRB2 research guy.
What's the point of making SRB1.5? According to the Official website, the staff knew that SRB1 was gonna be scrapped.
Technically the staff didn't make SRB1.5, it was actually created by a mutual friend of Sonikku and SSNTails and was
given a position as an "official" game since he had access to all the secret stuff and had all the power to put it on Sonic Team Junior's webpage at the time. As I said before, it was made in 2001 and STJR had moved well beyond the typical 2D Engine. Although it's unknown why it was removed in future crawls of the website.
