It's weird that the thing did not explode with the control rods fully removed, I designed it to go critical if the rods were removed over 70%. I appears that I have to revise the conditions for criticality
Thank you for your feedback! You are right, for some reason when I exported the WebGL version the death screen did not work. Unfortunately, I can't patch it until the end of the voting period.
Interesting idea! Had a good time playing it. Some ideas to improve it would be to have some effect if you shoot the wrong color to a shield. Keep it up!
