In this game many mistakes were made, a draw in the end. Can someone show me if there was anyway white or black could have gotten out of this?

Black's opening looked highly suspious, maybe 16NxN BXN 170.0.0 was better than 16Ke2. There were probably quite a few better options for white earlier.

        What was going on in the endgame where white had a mob of pawns for a rook, I couldn't say without spending a lot of time analysing it.Looks highly risky for white to go for this though because black can get his own pawns moving. 35g3 didn't look very constructive maybe now 35...c4 35kf4 umm white threatens  g5,f6 and rb8 mating. What a mess!

The game was very fun to play except I got way too overconfident and saced way too much.

About the endgame, I think it is truly a draw here, white have no time to activate it's second rook, while black is also kind of stuck and I don't see a way how to make further progress for either side...

Well isn't the mating threat I mentioned a way for white to make progress? Black can't move King or Rf8 without dropping material. Instead of 35g3, think white should get on with it with 35Kf4. Excuse me for saying so, but it was kinda obvious that white hadn't calculated much when going for this endgame. It looks quite possible that white is winning anyway, but my own lack of calculation power means am not completely sure.

If the king were to have gone to F4 I would move Rc4 and check. King would move then I would move Rb4, and thats game!

Ok you are right, and that makes sense of 35g3 .  Not sure what black plays after 35g3 if 35...Rf6 36Kf4 Rc4ch 37Ke5 Rb4 38 RxR pxR 39 KxR b2 40 Kg7 b1=Q 41 f6

Think white is winning in this line, too many pawns even for a queen. Black seems to be in  a sort of zugzwang after 35g3, were any move allows a favourable Kf4, or b-pawn drops.

if Kf4 on 36, Rc4, then e4....  Black then has to cover back on the pawn with the rook.  Are we talking the black counter to e4 was b4?  I guess that would be end of game.  White needs a few extra moves in order to be in mating position.  I really didn't see why white set up the double file of rooks on h and never used it.  I realize black could dodge behind rook to e8, but that doesn't leave much room to move at that point.  I would think that would lock down the rook on f8, because a move would allow gain of the queen unless it was moved sooner.  Oh well.  I think I would believe that somebody tried to get "too cute" with the bishop and rook for a pawn and a bishop attack by white....  That's strictly a "black makes dumb move, white wins" move.  In a game of two 1700s, I wouldn't expect someone playing black to make that dumb of a move....

I was suggesting 35kf4?, iso 35g3, overlooking 35...Rc4ch 36e4(  or...Ke5) Rb4. 35 g3 looks like a good move in fact, struggling to see what blacks after this...
