Yay! Glad to hear you could find the secret ending (with some struggle).
I can edit Iggs dialogue a little bit to make it more obvious about what you are supposed to do, especially in the 2nd half of the game.
And I'm hoping to have fixed the slow down issue! So it should *crosses fingers* run smoother in the finished version.
Can I credit you as a betatester in the finished version? What name and/or link would you like?
