I noticed the new updated on the Playdate Catalog and tried it out. The old crashes, which were very predictable (always the same place and time on a speedrun) are gone, but now I've been finding some new unpredictable ones. Also the new crashes take a considerable longer time for the Playdate to restart (went from a few seconds to up to ~24 seconds to restart).
I got a couple crashes captured on this VOD if it helps;
20:46 Audio starts to cycle and crashes at 21:01 with a quick restart (sorry about my own audio on this - my mic was dying).
31:56 A very long to restart crash with no indication the crash was coming with a long (24 second) restart.
Really appreciate the effort and time you've put into the game so I hope sharing these is appropriate and not annoying.
