This was a decent mod to play through. Making me realize just how far apart monitors were on big levels. One mistake can lead to you getting rekt by spooky blood eyes Sonic. Really adds to the tension with the removal of enemies and rings.
Some complaints, bosses were either a huge pain or downright impossible (looking at you VS Fang).
Maybe for bosses, Exterior can work like the Shadow Mario from Galaxy, if you stay in one place too long you die. Making players think before acting before going into a level.
Besides that, I had fun, and really made me put my map skills to the test!
Probably the most scared I've been playing SRB2, and I love how you can't even outrun Exetior, you gotta stall him. Although if you have one or two rings you might be able to just damage buff your way through any act, minus the bosses.
Okay, upon closer inspection, THZ2 seems to be impossible as Tails, because of the opening section.
And you can't carry over a countdown from THZ1 since there are barely any monitors at the end of Act 1. G r e a t .
I don't think it's possible to beat ACZ3 either, as ANY character, Bummer.
(From the previous review: the countdown also counts down once for EVERY player in the session, making it twice as fast if just playing Sonic & Tails (WHICH SHOULDN'T BE POSSIBLE TO SELECT ANYWAY BECAUSE OF SONIC BECOMING EXETIOR).)
