Both solutions are backroutes. I'll make a note to fix those in v1.02. I'm glad I made you work hard for the solution to Chaos 28 though!
LOL Backroutes.

My ideas really are goes totally burn out any other completion routes Chaos 28.

There is another Chaos 17 solution. Im not know which was this backroute last time?
How ever im not still are reach that 1:30 minutes talisman limit. Just have to look better
EDIT:
Added Talisman Solution Chaos 17
Time 1 min 21. 3 different solutions in this level, i think this talisman solutioin was same as game creator intended
EDIT 2:
Chaos 5 Perilous Parkous Completion solution
Its take me little bit time understand this idea, but that was quite simple when i pick up it, how ever i not have any idea how make this level nearly 20 seconds faster. Fastest Zombie is your keywork pass this trap IMO, have to look this better
EDIT: 3 Chaos 5 Perilous Parkour Silver solution
Very close 1:09:65. Sub 1:10 This way different than my orginal solution, but its actually even easier. This time limit got talisman was quite tough one, let try bronze solution later.
EDIT: 4: Chaos 5 Perilous Parkour Bronze solution
That was cakewalk 16 skill limit. This level is busted rightnow. Its actually identical like silver route, but that skill limit was easier than time limit
BTW. Okay I´ll try few more attempt to beat Chaos 26 (before bed time). This level look way too simple, but i somereason can´t figured out that. I might overlook some badly.
