Did my opponent give up too soon or am I missing something?

I’m black, it had been a very long and close game to this point. I felt like they were slightly in control for a lot of the game and were probably a more experienced player than me. My opponent resigned at this point and I was a bit surprised. It looks like their king can escape and they can promote their pawn. Am I missing something? Are they looking further ahead and thinking I’ll get to promote my pawn too and then they wouldn’t be able to recover? Or am I missing something more obvious like an inevitable checkmate?

I got a lot of opponent's good pieces but now my pieces can't move because of the huge pawn batallion

How do I work from here?

What do you think of this position?

It felt like a kind of funky position. What do you think? Is it a bad one? If so, any tips on things to avoid to get to this kind of position? Fyi I ended up blundering my queen later in the game and lost… (wasn’t paying attention)

Who is winning here?

I lost this game, as black

Proud of this one. 2 brilliants and 80%.

Forced a draw. Felt good as heck.

I was on beginner but this person was definitely NOT a beginner. Felt so good to not let them win.

Played Evans gambit, got to this position, computer says it's blunder, 'show moves' doesn't help.

Idea was to defend the pawn while also developing the bishop, sound good right ? Not according to the engine.

how did I win?

How did I win this game??

Guess what my opponent didn’t prevent from this position

this game hates me

Why did this end in stalemate?

This has happened twice now where I think I've got it in the bag and then the app tells me it's a draw?
