From the developer:
SSTap is a program used to “socksify” TCP and UDP connections at the network layer. It implements a TUN virtual network interface which accepts all incoming TCP and UDP and forwards them through an HTTP, SOCKS4, SOCKS 5, SHADOWSOCKS server, without any need for application support. It’s suitable for gaming because it supports both TCP and UDP protocol.
