Recent measurements in high-multiplicity pp and p-A collisions have revealed\nthat these small collision systems exhibit collective-like behaviour, formerly\nthought to be achievable only in heavy-ion collisions. To understand the\norigins of these unexpected phenomena, event shape observables can be\nexploited, as they serve as a powerful tool to disentangle soft and hard\ncontributions to particle production. Here, results on the production of light\nflavor hadrons for different classes of unweighted transverse spherocity\n(S rm 0^p rm T= 1) and relative transverse activity (R_ rmT) in\nhigh multiplicity pp collisions at \√(s) = 13 textrmTeV measured with\nthe ALICE detector are presented. Hadron-to-pion ratios in different S rm\n0^p rm T= 1 and R_ rmT classes are also presented and compared\nwith state-of-the-art QCD-inspired Monte Carlo event generators. The evolution\nof charged particle average transverse momentum (\⟨ p rm T\⟩)\nwith multiplicity and S rm 0^p rm T= 1 is also discussed. In\naddition, the system size dependence of charged particle production in pp,\np-Pb, and Pb-Pb collisions at \√s rm NN= 5.02 TeV is presented.\nFinally, within the same approach, we present a search for jet quenching\nbehavior in small collision systems.\n
