Mossmouth is still looking to fix issues, like the recent problem with invites.
Though it launched with a fair amount of critical acclaim, Spelunky 2 has had its fair share of problems this year. Its online multiplayer faced issues on PS4 and was subsequently delayed for the PC launch. Mossmouth has now confirmed that online play is in open beta on PC.
Unfortunately, while matchmaking is working, inviting friends has been problematic. According to the developer, “This did not come up at all during the closed beta, and we suspected that the addition of multiple servers in preparation for the (much larger, more global) public beta might be related to the issue.” A recent patch has helped sort the issue for a number of players but Mossmouth is still working on fixing any other issues that crop up for the time being.
In the first half of 2021, it will enable cross-platform play between the PS4 and PC versions. The Arena mode will also be tweaked while the invite system also receives some changes (though that will be for later next year). Mossmouth is also working to bring Spelunky and Spelunky 2 to Nintendo Switch in Summer 2021 so it should be interesting to see if online multiplayer is sorted by then.
