So I really liked this demo but, it does need some bugfixes/adjustments. I think the biggest issue is the lock/unlock cursor as killereks had pointed out. I wouldn't have been able to continue without their comment on how to make the cursor show up.
The slow walking and ability to move faster by running diagonally is a bit clunky. Some of the notes/items I didn't have time to read; the text disappeared too quickly off the screen. I think a mini-tutorial might be helpful for lockpicking (although it might not be necessary once the cursor is fixed).
Some of the character audio seems a bit low but the voice acting is really nice. I had an issue clicking on the security officer in the club because of the way the camera kept moving in and out so that's a bit frustrating. I did manage to finish the demo though.
I also really like the idea of finding evidence and linking it all together in order to try to solve a crime or gain a lead. I could tell a lot of work went into cutscenes and the main character's animations.
I'd love to see this game finished because I think it has the potential to be really good, if all the issues are fixed. Overall, I really enjoyed the demo and I'm glad the issues will be addressed for the final version.
