Congratulations on creating your first game! I'm sure your friends and family loved it.
I didn't know the story and my French is very rusty, but I understood enough to follow the instructions and know what was happening. What a delightful little experience this was.
For your first game, this is very impressive. You've got character movement, collisions, basic dialog, sound effects, parallax movement, animations and a fully narrated introduction. That's a massive achievement and it feels like a really cohesive whole.
The art style is so cute and the animations are lovely. I also like the way you introduced the controls slowly. I really enjoyed playing this. Thank you for sharing. As others have said, I hope you keep making games=)
