I believe this has something to do with your gains 
If they select one wrong, then your script will forever know that they have a wrong answer, because gains cannot be lost. I think your best bet here would be to use the point system. What you could do is something like this …
label bakery_trial
tappable
"FLOUR"{
@MG=0
}"BUTTER"{
@MG=1
}"EGGS"{
@MG=0
}"SUGAR"{
@MG=0
}
Then…
if (MG=0){
NARRATOR
Wrong ingredient, try again.
goto bakery_trial
}else{
NARRATOR
Correct! Next ingredient...
goto bakery_round_2
}
The same thing would be repeated for each round, but add a point for each round. Changing the 0 from wrong to being 1 for round 2, 2 in round 3, and 3 in round 4. Then the points for correct would match the round number. Round 1 was 1, round 2 is 2, and so on. Create a character to match the points added. Character name is up to you, I just chose MG because it’s quick and easy (stands for mini-game)
