Have you been itching for an excuse to make a JJ2 level? Maybe Treylina can help you out with 2-Week Jazz JAM #1: Quirky combo battle. Entrants have two weeks (less than that now) to make a battle level (or two, or three) using multiple tilesets. There is no prize for winning, but you can click through for more details and rules.
Or if you’re more interested in single player level design, there is talk of making a Holiday Hare ’18 community level pack as a sequel to last year’s HH17. Nothing concrete has so far emerged in terms of planning, but you can join in the discussion in this JCF thread.
Eat your lima beans, Johnny.
