You know, after waiting for a DoomGuy addon that has the exact feeling of playing DOOM in SRB2, i never was the same after that, with all of the DOOM weapons in the addon, and pretty much being easy to collect all of the weapons in Greenflower Zone due to the amount of badnicks, i ended up feeling satisfied after this, the only bad qualities is that in some stages it might be tough to beat when you're DoomGuy due to the weight and movement speed he has, leading him to be stuck in some parts, or some cheap deaths, but anyways, this addon really deserves some love to be honest with you, specially with the addon making SRB2 feel like DOOM, which makes sense considered the fact that SRB2 was on the DOOM Legacy Engine since October 1999 up to this day.
