I am hoping to hear from the dev on this one.

Battled my way through the last mission, completed the mission and the game will not progress to the ending.

It just sits idly.

Very disappointing end to a good game.

Edit:

Never mind, I see that you must manually end the mission then choose an unclear option to play a very choppy end sequence. Still a poor way to end the game.

I got all the mononliths and completed the game on challenge.

spoilers ahead so don't read on if you don't want to know



















The gameplay still runs at the end of the mission but just remains in limbo-no notification, nothing.

You actually have to end the mission manually, then go back to the mission selector and choose a new highlighted option resembling stars over the final mission. This then gives you the very choppy cinematic ending.

Possibly one of the worst ways I have ever seen to script an ending, such a shame for a very enjoyable game.

That certainly isn't intentional, for me the ending sequence played when I finished the last floor, just as you would expect.
