NA61/SHINE is a fixed-target experiment at CERN SPS which studies strongly interacting matter. The search for experimental signatures of the critical point is performed via a comprehensive two-dimensional scan of the phase diagram of strongly interacting matter by changing beam momenta (13A-150A GeV/c) and the size of colliding systems (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La, Pb+Pb). Recent NA61/SHINE results on the search for critical behavior search in two-particle correlations, multiplicity and transverse momentum fluctuations, femtoscopy studies and intermittency analysis were presented.
