Final Pot: t1140

This is a $4/180 tourney that I started up for the hell of it. My first instinct in this hand was to just reraise big or at least push after the reraise push by te short stack but then I thought (overthought?): It is the first level, I can probably outplay my opponents at this level in the long run, I should give some credit to an UTG raiser even at this level, if I miss the flop I am out of position and if I am sharing cards with others who come along with the action I am a much bigger dog than a coin toss and I wonder what FE I have at this level. I am also unafraid to see a flop multiway since I don't have a vulnerable pocket pair. So... I have reasons why I played it this way but I still feel so... unfulfilled (and the outcome has nothing to do with this feeling).

Help me...
