Atomic Chess: How to Defend Against White's Early Knight Attack?

White can play 1. Nf3 on their first move and then play 2. Ng5 threatening to blow up black's kingside, or even worse, 2. Ne5 and then threaten to blow up the black king no matter what.

1... f3 seems like a reasonable way to prevent white from advancing the knight to either g5 or e5 but at the same time that opens up the king on the h5-e8 diagonal. 

Is 1...f3 the best response for Black? While it stops the immediate knight threats on g5 and e5, doesn't it weaken Black's king position significantly? Are there other ways to develop the pieces and defend the kingside without such a risky pawn move?

You can play this vs a new player in Atomic if you're black: 1.e4 d5 2.xd5 Qxd2#

I mean other than f6, there is only e6 or e5, and tbh those are not that good tbh

Ng5 followed by Nf7 is looking like a +6 eval to me

...f6 is the only good answer to 1.Nf3 in Atomic. Then 2.Nc3 (threatening Nd5 and Nb5) Nh6! (...c6 also works.) Black is threatening to murder white's king with ...Ng4. 3.g4! c6 and the position is playable for both sides.
