"It was great and I had a great time," he said. "It was a quick visit, but overall I had a great time. I had a great time at the game and I had a great time with the team after the game."
Kamara arrived just a half hour before game time and left at 11 a.m. Sunday, but said the visit still showed him everything he expected.
"I talked to the coaches, coach (Mark) Dantonio, toured the facilities, talked to coach (Ken) Mannie, the strength and conditioning coach," he said. "I got a good tour of everything today in the morning and got a tour around campus, so pretty much everything you do on a longer visit but just condensed.
"It was a short visit. They made the best of it, though."
The 6-foot-2, 205-pound receiver said the game atmosphere was the highlight of his visit.
"It was crazy cause everyone on campus was really pumped up," he said. "There were a lot of Michigan fans there, too, so there was a lot of tension before the game and after the game but during the game it was really good.
"Everyone was all hyped and ready to go. It was crazy because all the fans were talking trash. It was a good time. I really enjoyed myself."
He also said the play of the wide receivers stood out and how well they played – as well as how he could fit into the offense.
"They threw a lot of fades and that stood out me," he said. "I like the fade route a lot. They were throwing the ball to No. 13 a lot. I noticed him. No. 13 and No. 14.
"I could (fit into the offense). I like the fades and they check to the little 5-yard stops when they get one-on-one coverage and they got deep. I like how they do that. They run intermediate patterns, too, so that was a good thing."
Kamara, who plans to announce his college decision at the Army All-American Game on Jan. 4, said the visit put MSU in his top group with Wisconsin, Pitt and Virginia.
"I have a top group, I have like my top four and they're in there," he said. "The visit definitely made them one of the hats that will be on my table."
Kamara already had taken an official visit to Wisconsin and will visit Pitt on an unofficial with his coach next weekend.
