My best friend texted me that they won a game what do I say?

P̶o̶s̶i̶t̶i̶v̶i̶t̶y̶.

I told him that I forgot to go to the game cuz I missed school today and so then he told me that they won't the game what should I say? If I say good job I feel like he's gonna cringe or sum. 😂 what should I say pls something not cringe
