Firstly - Thank you so much for playing my game ^.^ That's awesome, and I appreciate it.
To answer a few things:
The gargling sounds are not supposed to be 'pleasant'. They're supposed to be silly. =^.^=
In order to retrace you can hit ESC so that you don't lose your progress. Sorry that I wasn't able to get a note in for it.
I had fixed the disappearing text on the tutorial previously, but it sounds like I broke it again with having to redo some things. The "pay attention" is because although you have tutorial instructions I don't give away exactly how navigation interacts with other objects. ;-) Duck Physics are simple, but fun.
I'm not sure what to do about the game being small on the itch.io page to be honest. My existing skills are primarily in art, music, and storytelling moreso than coding. I'm sure I'll figure it out though. This is my first Jam as a solo dev; so I'm pretty happy with how far I made it in just a few days <3
Thanks again for playing, and the feedback!

Regarding the full screen option, it's a simple checkbox you can enable on your itch project "Edit Game" page. Scroll down to Embed options section and you can find it there.
