Yeah, I wish I would have communicated how I wanted SRB1 mode to be used to the devs better. I wanted it make it so the modder could use either 2d mode if he or she wished. Having the user unlock the mode to use it defeats the original intent of it.
I think that it might be better to merge the 2 modes with some modifcations so that it will always be better control over the character in 2d. That way the user won't have to choose from A. normal 2d mode B. better 2d mode controls, but you have to unlock srb1 lol
