Nice artwork! Though I have to admit, I love pixel art, but I’m not a fan when sprite sizes are inconsistent - it just feels a bit off :D
I noticed an issue where clicking on 'Controls' caused the entire UI to shift out of place, but this was only a problem when not playing in fullscreen. Also, when falling, it would be great toactually fall through a complete scene rather than ending up in empty space. The tileset looks nice overall, but the scenes themselves feel a bit empty, with some sprites placed somewhat randomly and not always matching the overall art style.
The dialogues were a real highlight! I especially enjoyed the friendly conversations with enemies right before they attacked - such a fun touch. It would be helpful to have clearer feedback on checkpoint locations though.
I wasn’t able to progress past the boss. I assumed I needed to jump onto the platform, but I just kept falling through. After another try, I already gave up since it was quite challenging. As a platformer, you incorporated the theme well through the dialogues - great job on that! Overall, a nice little game with lots of potential.
