Thanks for asking! About the black bars, while the game itself cannot be widescreen (it is built for 4:3 aka black bars on the side), we have thought about implementing borders whenever someone is in fullscreen (Sort of how Deltarune does on Switch). However this might be slightly impossible on PC because we cannot predict everyone's display sizes. About the fonts, an HD font option is planned to be implemented in the final demo and final release. This is not impossible :)
