As You See In The Title "What Is The Topic"

All I see that could be considered a topic is "something playful".

the theme is : Tulipomania.

Maybe the theme will be more visible if included in the jam title? But I'm afraid it'll grow too big with some themes...

im sorry but the tulipomania theme i couldn't understand

No problem. Maybe the theme should be included in the picture, so that it will be written in huge bold letters.
