In the game, Kenji gets 10 points for finding a Silverthorn Dragon and loses 6 points when it scorches him. To find his total score at the end of the first level, we can calculate it as follows:
Starting score: 0 points
1. Points for finding the Silverthorn Dragon: +10 points
2. Points lost from being scorched: -6 points
Now, we can calculate the total score:
\[
\text{Total score} = 10 - 6 = 4 \text{ points}
\]
Thus, Kenji's score at the end of the first level is **4 points**.
