I want to thank the game's developer for updating this old game :) It's an old game, but it's fun to play I'm planning to get a new Mac and before I saw that this game was updated, I thought that it wouldn't be playable on the M1, since the old version was 32-bit... but then I saw that there was an update... The 1.5 update is 64-bit, so it should run on new versions of macOS. The single-player game is also an "Universal Binary" now, so it should run natively on M1 (without Rosetta)... The multiplayer game seems to be just a 64-bit Intel binary, but it should run in Rosetta. I'm hoping the multiplayer game eventually becomes an "Universal Binary" also, to kind of "future proof it" better in case Apple eventually stops supporting Rosetta.
