fix: els globos tenien un parell de setters mal asignats per culpa de buscar y reemplazar

fix: els globos verds s'inicialitzaven amb vy = 0 per gastar abs en lloc de fabs
fix: corregit un bug milenari que de sempre havia creat els balloons verds al popar al pare amb la meitat de velocitat en y. Lo que jo no se es com anava res. Supose que ara el joc serà un poc mes xungo. Quan rebotaven en el piso ja se'ls posava la velocitat bona (crec)
