RE: Crashed and not exactly sure why
You made every possible mistake to cause this problem. From a slow speed and probably nose high for landing you slammed full power which caused torqueing and turning. Then you raised the elevator instead of just maintaining altitude and letting speed build and keeping the wings level with the rudder. This probably stalled the plane or snap-rolled it.
3 things are wanted on a go-around. Maintain altitude, gain airspeed, gain altitude in that order. THEN turn off runway heading. Deviate from runway heading only to avoid obstacles (people).
