This is an addictive little game, there's an urge to find all the keys, but even with replay it's still a pretty short game. The keys are a little hard to see, I got down to one and searched the whole house a few times before being caught and never caught a glimpse of it, even with it being highlighted. So there's a lot of trial and error with learning key locations, or just blind luck. The butler isn't too hard to avoid once you understand him, being faster than the player makes it tricky, but the truth or lie mechanic gives you a little wiggle room to use. A pretty good game, I think it works fine as it is. Maybe as a learning resource for a bigger game.
