Antichess: is 14-moves game possible?

When I just began to play antichess, I thought that the shortest possible game is 17 moves. It's simple: there are 16 figures to take and taking on 1st move is impossible. Recently I have found a variant with 16 moves (1 pawn is blocked) and today I've found 15-moves variant with 2 blocked pawns.

1. e4 b5
2. Bxb5 Nf6
3. Bxd7 Nxe4
4. Bxe8 Qxd2
5. Qxd2 Nxe2
6. Kxe2 Rg8
7. Bxf7 e5
8. Bxg8 g6
9. Bxh7 a5
10. Bxg6 Bf5
11. Bxf5 e4
12. Bxe4 a4
13. Bxa8 Ba3
14. bxa3 Nc6
15. Nxc6#

Does anyone know a 14-move variant with 3 blocked pawns or it's impossible? If it's impossible - why?

Intuitively it seems like it would be easily possible if you were controlling both sides, but of course I don't have a solution.

I've just found 14-moves variant.

1.e4 b5
2.Bxb5 Nf6
3.Bxd7 Nxe4
4.Bxe8 Nxd2
5.Bxf7 Nxb1
6.Qxd1 Nc3
7.Qxc7 Nxa2
8.Rxa2 Rg8
9.Bxg8 Be6
10.Bxe6 Na6
11.Rxa6 g5
12.Bxg5 Bh6
13.Bxh6 Rd8
14.Qxd8#

I think this is the shortest antichess game.
Thank you for good puzzle.

I searched among my games and this 15 moves game has really happened
