Nice little platformer!
Pretty cool theme use with the food and happiness meters. I liked that it incentivized you to move quickly through the levels, and it makes each jump feel like it counts.Definitely makes the game feel tense, and like you're really dashing to escape.
An exploit I found: When you die, your misery doesn't get reset, so you can repeatedly eat high -misery food and die to farm up happiness, and then you can eat as many weird foods as you want without issue.
Also, I think an open door sprite would be helpful. I had a few instances where I got a key and tried to go to the door it opened, but couldn't remember exactly where it was and ended up getting lost and dying when I'm pretty sure I went past it once or twice. But besides that, I thought the visuals were very good!
Great job!
