...does the 3w 100 ohm resistor tell what?
Since there was a considerable current running through 100R resistors, there is a chance that your MOSFET is dead - check it and you'll know - please don't ask "how do I check if the MOSFET is OK?" 'cause you'll be the 10,000th member with the same question and they'll be obligated to reward you with a 7-day Bahami cruise tour...
You have learnt your lesson.
It might actually be quicker to build another one with new parts on a fresh piece of proto board
