But when I tried to use TNT, the TNT ignition speed was too slow.

So  please revamp tnt.

For example, just as gunpowder can be used to control how long a firework rocket stays in the air, what if we could also control how quickly TNT explodes?
Or how about igniting the TNT with a flame enchanted bow so that it explodes instantly?

I hope you have some good news about this idea.

And this is a different opinion, but I think tnt is too bad at breaking rocks.

Then have a nice day, Mojang
