Criticism
This sale has sparked criticism due to shorter timers than usual, long delays between waves, the lack of limited items (currently), and no classics other than Bighead and the Workclock set. In addition, the Emerald Valk Shades originally had a 12-hour timer, but due to an unknown reason the timer was removed and the item was kept available. Compared to other sales, Roblox only released one expensive accessory for the Bighead.
