A flexi disc with a remix of Summit from the Celeste soundtrack was included with early preorders of the Celeste B-Sides vinyl release from Ship To Shore PhonoCo.
The flexi-disc is designed to look like a PICO-8 cart. It was designed by Drew Wise.
It released alongside copies of Celeste B-Sides purchased through Ship To Shore PhonoCo. in early July, 2019.
