I really liked the little details like the menu being the controls, belly growing larger (looked really smooth), etc
It took me a bit to find the 20 second timer (not super legible against the background) and I'm not entirely sure what the progress bar is indicating (seems to go from red to green while eating and not fill back up / change regardless of how much I eat). Would be really cool to see different variations on endings/outcomes (I had one play through just now where I ate nothing and somehow still died of a heart attack, for example)
Really liked the style overall!!
