Thank you for the feedback!

The version number will be included in the next release (introducing a main menu where it will be displayed). As for the enter/return bug, I'll take a look to how I can fix it - I may need to replace the TMP Input Field with my own if there is no reasonable way to do so.

EDIT: Has been fixed now, and a new version is available with the version number. We are starting at...... 0.0.0.9 as I was sort of recording the versions via builds locally.

This is due to not having a "default" value for when you get no score - same for the question marks. I will update this functionality with the Main Menu update, well spotted!

Edit: Has been fixed as of 0.0.0.9 now! Now instead of trying to divide by 0, it instead returns a default value (0%), and returns 0 instead of question marks for the rest.
