Apologies for entirely forgetting to specify my system information. I installed the game using the itch.io app in Windows 10 which I believe usually makes it the latest available version of the app... but I've just double checked and it looks like it defaulted to the Jam version, so yes, I will need to double check this lot - apologies... I be back to you with what I can find once I've played the latest version. I have to say I'm a little perturbed as every time I've had reason to check previously it was indeed the lastest version installed by default, I wonder what happened this time?
