Tidal Wave is an unrated 2.1 solo Extreme Demon created by OniLink and verified by Zoink on 9 September
2023 after 49,534 attempts.1 It is notable for its three-minute length, wave-
based gameplay style similar to that of a Nine Circles level, its uniquely bright
summer/beach theme and 200 frame-perfect timings,2 more than double of any preceding Demon level. Tidal Wave received a generally positive reception from the community, with praise for its unique theme and length but criticism for its
high object count. OniLink had optimised the decoration from around 303,000 objects to 255,366 objects. Tidal Wave is
set to place at #1 on the Demonlist, surpassing Acheron
