Thank you for playing, I'm glad you enjoyed it! :D There's actually a hidden walk option which cuts your speed in half and has no use at all... A sprint would be nice, moving faster but also making more noise. I wanted the guards to be able to hear the player as well as see them but I didn't have time to implement that.
I've had lots ideas about the gaps and I think I should be able to come up with some changes so finding them is less frustrating. :)
