Version 1.4.1 is out. Mainly quick bug fixes. Enemy gendoors and killdoors should also work on already gendoored enemies! I feel like I missed some edge cases with it, so as usual please report bugs related to it!
Version 1.0.4 released. If you have an older version of the game, you can now also download the patch zip, which only contains new and changed files. Replace the old files with the new ones and you should be good to go.
