Didn’t know about Cranko! Ordered my copy. Keep up the great work!

Those devlog updates are always a highlight for me, thank you so much for so many detailed insights!
Your paragraph about the hassle of trial and error when iterating on animations inspired me to work on a tool during our last company hackathon: With Playdate AntiMirror you can at least stream and review in real-time your desktop content on the Playdate. It's not quite the animation engine you were describing (I am thinking if "Rive for Playdate"), but I hope this is of some value for you!

Nice find, thank you for reporting! I have ideas how it came to it and how to address it, but proofing that it was fixed will be time-consuming  🪫

EDIT: hopefully fixed with as part of rework of screen updates for button support.

I just uploaded a new version with the following changes:

• 🆕 no more autolock of the screen for watchfaces (currently, Intrinsic Gravelty will lock. Later, games will too)
• ↗️ various power optimizations so that rendering (or processing for Pebble apps) only happens when a watchface needs to update (e.g. once per minute/second depending on their use of TickTimerService)
• 🆕: correctly propagate Playdate's battery level and 12h/24h clock mode to the corresponding Pebble APIs
  • Note: while Pebble's BatteryStateService would allow watchfaces to show charge + plug state, Playdate's equivalent API is seemingly only available for Lua apps. I created a request on the DevForm about this.

EDIT: It seems as if the battery will still not last for even 24h despite my efforts to reduce the refresh rate to 1.0 FPS doing minimal logic only and no redraws. I will try to optimize further, but right now you can only use this as a desk clock when also connected to power.

Great feedback, thank you! Yes, using Playdate as a desktop/night stand when showing Pebble watchfaces is certainly something I would like to support – ideally even with the upcoming https://play.date/stereo-dock/.

The SDK certainly allows for this, but right now, Gossan refreshes unconditionally at 30FPS and would burn through its battery in no time. I captured this in my backlog and will distinguish between interactive apps (aka games) and passive experiences (watchfaces and demos).

Topic to discuss the closed beta for Gossan on Playdate. Anything from "I wish Gossan did X" over "I was expecting something else here…" to "I think I found a bug" is highly appreciated.
