Demo 1.2.1 is up for testers, however there is currently only one who had decided to undertake this task so far.
As it stands, the main story is virtually clear of bugs, aside from minor complaints and needed embellishments. The epilogue itself is what is in the most need for bugtesting.
If you have an ending code from the content folder after playing through the game, it can be used to access the epilogue in 1.2.1, no matter which ending or version you got it from. Those that have played through the original release would be preferred for bug-testing in this case, as they will be able to skip to the epilogue much faster.
Please inquire via PM here or on discord if you are interested. Thank you.
