I'm impressed by the arts and animations, it was also very fun to play! My main issue was the amount of time between the transitions, where the time would keep ticking. A few times I had reached the end of the corridor with the lasers and the screen faded to black but the timer was still ticking, and after 5-10 seconds it gave me the lost-screen. :(
I liked that each step, or level, had its own little challenge, it made me want to try again to do better. :) Good one!
PS. found a bug I'm sure you already know about but I'll toss it in there anyway - when I picked up gold and didn't make it back in time, I would restart but keeping my gold in the inventory.
