ah yep, we're working on the ironing out the bugs! there's a bug with the beginning of the game, so it's not your fault at all. should be fixed in half a day to a day (most of the team stayed up all night working on the jam)
The build for the first ending is up! Unfortunately Unity has been extremely unkind to me this weekend and decided to nuke all the textures in the build containing the second ending when exporting, so the build with the second ending may not be available until that's fixed.
