Glacial was one of the entries for the 2018 RISC-V SoftCPU Contest, but I think it wasn't ready by the deadline. If you look at the winners there was another 8-bit CPU with a RISC-V interpreter, SERV, VexRiscv but also Reindeer which seems like a more balanced implementation: https://riscv.org/blog/2018/12/risc-v-softcpu-contest-highli...

SeRV is 1 bit ALU and datapath ("bit serial") PicoRV32 is 8 bit ALU and datapath. VexRISCV is full 32 bit ALU and datapath.
