My critique:
FYI I don't usually play these kinds of games, so I might not be the best judge.
1. I liked the story, but I feel like there could have been better mechanics around it rather than just pressing buttons. I also ran into a couple code errors while fighting wily, so that was dumb.
2. I didn't particularly like the art style, but it was consistent throughout the game and I got used to it. Definitely a forte.
3. I liked the sound, I just have one suggestion: There needs to be little blips bleeps ect. when letters appear, if that makes sense.
4. The concept was stolen from Charlie and the Chocolate Factory, but I still enjoyed it, especially the "twist ending" of the children in the candy.
Overall, amazing game with a phenomenal amount of content for 2 weeks. Keep it up!
