Busy Night - H4M-W2R-PJG
One of the most fun levels I've ever played actually. Really really enjoyed it a lot :D
Also very doable lvl (though the tower in the middle is tricky)

~4h, 1.5 nais, 10 POW deaths

3 sick waffle lvls :) - 4Y2-MKD-60G
Afterglow, Hypercube and Flamewall respectively are really neat NSMBU lvls. Really love 'em all tbh.
Especially Flamewall was soo fun. (+got WR on it)

nai 9 and 17 respectively (fortunately got the clear like 2-3min after nai 17)

Valhalla - LWR-0K3-V4G
such a sick vertical drybones lvl by Zeno :D
Gets really fun and consistent with time but learning was a little unfun. POW drop and nai are the hardest parts of it!

24h15min, 17nais in the revisit

and here are my 6 chokes

Gremlin - 47G-KGQ-9QF
Incredibly fun bomb lvl by Kuro.
If you're good at POW carries and POW triples, this lvl shouldn't be too difficult imo. Also, this last hidden block at the choke sucks :(

11h15min - 9 nais, 6 chokes

Blades of Forsaken - 5XN-WMV-7TF
WOW, beat this in my revisit within about 1-2h, no prenai or nai (in the revisit), wtf. Finally done with it, super fun level, pre nai has been rough for me :)
~40-50h overall (26.5 prenais, 0 nais)

Delirium Trigger - 7HY-1TR-20H YATTAAAA
Finally beat this monster by ev_brak.
Such a cool level to this day, painful grind though sadly.

30 cape deaths, 29 pre nais, 4nais
~34h (+15h from back then)

Salt and Jay's New Year Special - 92C-000-LGF
Really clean collab between the guys in the title :)
Took me a little too long, especially as the line up prior to the drop near the end didn't like me :(
4nais

Red Castle - TQ0-T2X-MTF
Super sick juggle by @waffle_chop. Really surprised it has so little clears honestly. Level felt really specific but pretty fun imo.
GO PLAY IT!!!
~5-10h, 2 nais, no choke

Yt-link: youtu.be/PokV7cCxWeI

Breadsticks - 136-N47-9XF
super clean collab between salt, jaysif and khaos :)
Very doable lvl although 2 tricks in the beginning can be a little inconsistent/weird
~3h20min , 5.5 nais

Fade Away - R27-DG9-B7G
Really neat juggle by zenfoh, that has been on my mind for a while :)
6.5nais

Niflheim
began building this right after my HoH upload, did so over a span of 2 or 3 months iirc. Uploaded it a year ago now and got deleted within 2 days because of a "glitch".
Probably my hardest grind to date, not sure though.
My proudest ever built lvl next to HoH!

Eventide Equilibrium 5YW-B3X-70G
informally the successor to Fresh Mint. Still pretty happy with how it turned out back then :)
