Sorry for comment-spamming BTW
Anyway, nice idea with the sparked wall for activation +1 and one ending-tip: Use the console and type in: !set life deut 99999 for a bigger and laggier BOOM xD (Comment was too long...)
You should delete the tags :) BTW my pc survived at fancy view with more than 4 FPS. And could you please add a sign saying that you have to spark the metal please? And a third tip: Better don't only make nukes because everyone makes them, better make some things with electronics or spaceships or stickman-run or... I think you know what I mean xD
