Thanks for playing and taking out the time to write a detailed feedback. I really appreciate it!
The thing with the fat and protein not hitting the villi correctly was a bug I couldn't fix in time. I didn't want to have any random lies in the game because as you said that would be trolling and not lies. There's only one lie per level and they're all in pink. My intention was to have the player know exactly what the lie was because of the change in color and then just treat it as an obstacle for that level. I probably should have made the lies lot clearer though.
Your feedback's been very helpful and I'll keep it in mind when improving the game. Thanks again! :)
