For each positive rational number epsilon, the theory of epsilon- stable quasimaps to certain GIT quotients W parallel to G developed in [CKM14] gives rise to a Cohomological Field Theory. Furthermore, there is an asymptotic theory corresponding to epsilon -> 0. For epsilon > 1 one obtains the usual Gromov-Witten theory of W parallel to G, while the other theories are new. However, they are all expected to contain the same information and, in particular, the numerical invariants should be related by wall- crossing formulas. In this paper we analyze the genus zero picture and fi nd that the wall-crossing in this case signi fi cantly generalizes toric mirror symmetry (the toric cases correspond to abelian groups G). In particular, we give a geometric interpretation of the mirror map as a generating series of quasimap invariants. We prove our wall-crossing formulas for all targets W parallel to G which admit a torus action with isolated fi xed points, as well as for zero loci of sections of homogeneous vector bundles on such W parallel to G
