Overall looks good and the story grabs from the start! I do recommend showing the dialogue controls the first time, because I got stuck for way too long on the first dialogue bubble hahahah. But anyways it is a very beautiful game to look at and im very interested in the ways you will continue working on this game! Good luck!
1 bug I stumbled upon is when you backtrace in level 8 where you can go back down my game gets softlocked. because it does not go to the previous level. I absolutely loved playing through those levels again tho!
Please also make sure to give my submission a try. As someone who isnt as experienced as you in pixel art I am very curious what you think about the looks of my game!
