Download watchface code or help with random function

Hi Folks,

I was designing a watchface and it was going pretty well.
Check the watchface out here: Chaosghoul - Pokemon (Seadra vs Tyrannitar) - watch face for Apple Watch, Samsung Gear S3, Huawei Watch, and more - Facer

I wanted to do something now that I either just don’t know how to do (at all) or is not possible with Facer, as the functions you can do are too simple.

What I would like to do:
Switch the Pokémon out every 15 minutes for another random one (I’m aiming for 2nd gen so it’s 252 different .png files).
I know how to do static changes, but the random part is pretty important to me. I’d like to set a global function that activates on minutes 00, 15, 30 and 45, grabs a random number 1-252 and sets transparancy of the equally named “number”.png to 100 and leave the rest on 0.

If this is possible with Facer, help would be greatly appreciated :smile:
If this is not possible (because Facer can “only” take functions on every single picture): Is there a way to download my watchface so I can edit it with android studio? I’d hate having to redo everything I did so far there.

Thanks in advance,
