Paradox Junction's Easter Egg is Horribly Designed

The first issue: Cooldown on the timeswap

The timeswap sucks, oh my god. I love having to spend 1,500 points and 2 whole rounds waiting for it to recharge so I can actually progress the EE, also, sorry that the random ass timeswap resets ANY Steps you were working on. Trying to upgrade the Blundergat to the Sundergat? Sorry, timeswap mid-zombie lead, bye bye! No more :>
Also, christ almighty what is up with the fact that doors opened in the future don't open in the past? It annoys the hell out of me that the first time you time swap, you can't do ANYTHING, NOTHING. No doors, gotta re-open the whole map, and then unlock Pack a Punch.

The second issue: Sundergat being required, despite being absurdly hard to get.

I understand its "easy" if you practice, but it requires so much precise point grinding and absurd timing and PRAYING you get lucky with the spawns of a zombie that dies if he breathes wrong. Also, the amount of steps that require low zombie counts to even be done is awful, oh my god. The piano teacher, the zombies for the sundergat, you progress so many rounds BY ACCIDENT doing this shit. Seriously, I was doing the final trial on a run on round 36 because of how many rounds were being flipped by accident. All of this sucks.

This whole map is a gigantic skip. The easter egg feels like it requires you to run the Round Off gobblegum and Gift Card to even complete it within a reasonable round, the amount of RNG required is annoying, and the middling reception.

(AVGN Tone) What the hell was treyarch thinking?
