To play a video game, Doraemon must pass 10 levels. It scored 90, 84, 81, and 93 points when it passed the 6th, 7th, 8th, and 9th levels, and its average score for the first 9 levels was higher than the average score for the first 5 levels. If the robot cat wants to get an average score of more than 88 points after passing 10 levels, then how many points should it get at least when passing the 10th level? (Scores are all integers).
