It's likely worth looking into federated learning. You could have a core model, which then trains locally on player inputs. The federated learning research space is focused on this sort of small model update on phones, so should have plenty of people who have thought hard about the problem of keeping binary sizes small and training compute manageable. https://arxiv.org/abs/1909.11875 https://arxiv.org/abs/1909.11875
