The required non-spawning candies are very difficult to obtain.
With the two non-spawning colours on the main board as well, there can be up to 5 colours. Making matches is extremely hard with five colours on the board and liquorice swirl (which thankfully don't respawn).
Chocolate can eat lucky candies and non-spawning colour candies, making things harder.
The order is worth 3,300 points. Hence, an additional 6,700 points is required to earn one star.
This was the first 4.6 coloured level (4 coloured level where two non-spawning colours can appear out of lucky candies due to being required as part of the order) which also requires blockers. The second level is Level 2669
Were it not for the redesign, this would have been the first 4.6 coloured level. After this level itself was redesigned, this is unofficially the first 3.5 coloured level. The first official appearance of a 3.5 coloured level is level 3622.
