The booster?
No.
It depends.
When you begin a level, the xor'd value is 0.
Use one booster.value is 1. Use another, it is 2.use 3rd it is 3.
What's nice is if you used all 3, start a new level and continue search. Now before will be 0 again.
What makes it easy to find us you'll have 4 values all in a row. Xor key xor val xor key xor val
First pair and 2nd pair won't match as xor key goes. But when you check the key with ida values, they both will match how many boosters you used.
Can edit and freeze all 4 values to 0 and be all set until you close the game.
