Using TNT

[CodeMouse92]

This is along the lines as #7 or #8, but is the most complicated of the three tools.

Power level corresponds to blast radius. (The actual in-code rules for blast radius should be coded in a maintainable way, not hard-coded.)

The proposed corresponding blast radius and power level is as follows:

7655567
6543456
5421245
5310135
5421245
6543456
7655567

(You're welcome to suggest changes to the above.)

The hardest part is, once the player sets down the TNT, the character must automatically pathfind to the nearest safe space outside the blast area, and then move there at double or triple normal walking speed. After the explosion, the character must automatically move back to the spot where they had originally been when the player placed the TNT.
