Hey H_Labs! Thanks for checking out the game.
I agree with you on the walking speed, I often upped it quite a bit whilst testing the different story branches. Instead of upping the base speed however we'll most likely introduce a sprint mechanic, which should increase the pace without significantly changing the story experience. The combat system was one of the last things we added and we could have implemented it better, the delay between actions can be frustrating.
I'm glad to see you're still pushing on through the story to explore all the different branches, there would have been more dialog if there was time but as you say, we already packed in quite a lot in the time we had.
We'll be releasing an update in 2 weeks when the rating period is over that addresses the issues you highlighted as well as expanding upon the story as we have a fair bit more dialog but didn't have the time to code in the mechanics. If you enjoy this sort of game and the genre in general then be sure to check back once we update and we'll welcome anymore feedback you might have.
