I really appreciate how much feedback you've given us! Things like the manual having filler text and lacking a pause button were, as you mentioned, in by design, but it's understandable how these can be overwhelming to some players. In the future we might look into making the controls stand out more as it's also been something many players mentioned. The fullscreen scaling issue is because Unity automatically applies antialiasing on fullscreen if the window resolution is too low (Wing It runs at a windowed res of 1280x720), so that is also something we might look into fixing in the future.
Again, thank you lots for the feedback, and I'm glad you still enjoyed what the rest the game has to offer!
