High gas prices on Polygon network

I was using Polygon network because it was scalable and cheap. Now a stupid game contract (0x6e5fa679211d7f6b54e14e187d34ba547c5d3fe0) is guzzling a lot of gas, everyone pays at least 500 Gwei now (instead of 30) to transact with the network.

This is only one single game on the network. How can we expect for the Polygon network to scale to thousands of applications?
