I really liked the experience! :)
First, the overall theme of playing as an Agent, needing to be careful what to say so as not to uncover your identity. The characters development was nice too, especially I liked how manner of speaking resembled their characteristics and backstories, that was definitely a plus. I also enjoyed the way you've "smuggled" the tip regarding the order of correct digits, that was both smooth and kind of tricky!
Graphic design combined with music give the player the ability to "dive" into that nice, gloomy atmosphere, and in the end I *really* rooted for the Rebellion, wishing to kick the Emperor's arse. Looking forward for the next part!
On the downside, as few others have mentioned, there's a bug regarding one of Doctor Death's dialogue option, leaving no ability to continue. Also a few graphic glitches, and, personally, I think it would have been a nice touch to add some kind of ending screen to dialogue options that lead to failure, even simple "you failed the Rebellion" or "you died", because currently, after selecting them, it also seems as if the game 'stops' and nothing happens, the player doesn't have that feeling of "it's the end"
