It's good, but could be better.
In essence, it reminds me of Wonder Boy. The type of character that needs of food to keep his bar from gradually depleting. I believe many other reviewers already posted this, but you should really think about correcting the time limit on the penalty for not eating. The bar moves way too fast. In fact, you should not put so much emphasis on the velocity in which the bar depletes but in the level design, forcing the player to be more astute and precise in platform jumping other than just trying to race against the hunger of your character. Also, some music would help as well as some checkpoints. The character could be fairly better designed too, maybe even keep the subject matter continuous. I mean, you got a character eating pizza. Why pizza? Why the main character is a sort of blue monster? Anyway, these are some ideas. I really like where your game could go and I'd love to see a new version of it. Keep at it!
