Hands down, this is one of the worst level packs I have ever seen, or had to witness, and the key word is witness. It's nothing but loud sounds and bright flashing colors, I thought I knew what I was getting into, but I draw the line at jackass level design, and ear rape. And to make it worse, people are giving it positive reviews, despite not giving an explanation besides "It's good, I promise", it's not good, avoid this mod, play something else, and the only people who like it are lying to themselves, or hate living in general. and to add salt to the wound, we could've had an actual classic ported to 2.2, but instead we have the go deaf for admin with new epilepsy mode. final verdict: this mod is JUST BAD.
I also can't comment on the lagginess of those two stages as I believe they're most likely meant to be intentional.
IN THE WOUDS also has an exit although I might have improperly included one of the two that are supposed to be there. Trust me, it is beatable, it's just a wee bit trollish. Will be fixed in an update though.
