The idea of the game is simply gorgeous. I didn't find any joints. The graphics in the game look forgotten, reminiscent of drawings in notebooks from school.
Thank you for your answer ! Because we didn't use a game engine, we had to code every single thing which gave us less time to make the art. By the way, if you get to the end of the game, the win image was generated by OpenAI's DALL-E 2 ;)
