TL:DR - TRY TAKING THE CASE OFF(?)
This is such a fun little game - The vibe is pretty much perfect for me, especially how absurd some of the dialog is, and feels like the exact kinda thing the Playdate was made for.
Unfortunately, I was having the same issue as some others regarding the shredder not hiding when re-docking the crank, which kinda ruined the game a bit. Wanting to try and work out if it was just the game or if I had a slightly dodgy Playdate, I did a bit of digging with the input test (settings>system), and turns out, I think it's an issue with the case - the console is noticeably less responsive to the crank being docked/undocked with it on. So if you're having this issue, may be worth testing this out - I now only fail due to my shitty reaction speeds!
