Very interesting concept ! Well executed too as the animations, music and gameplay is pretty solid. I like the idea of having multiple actions for the cheaters.
(Really enjoyed the acceleration in the music to build the tension).
Now I feel like there are some improvements that could be made.
It could be nice to have a slower first level to be able to familiarize with the UI. There are many things to read and understand, and I didn't really know what to do when the first day finished. (I still don't really get what is the crimometer :/)
It could have benn nice to be able to click on the suspect portrait and grey them when we think that they are not the cheaters. In the end there are a lot of characters to focus on, and I wasn't sure which one I already followed.
Being able to fast forward the day when all the cheaters got caught would be a nice feature.
Personal opinion for that (so maybe not a good idea ^^), but at first, I thought red machines were low% winning rate, and vive versa for green machines. Maybe it is because I visualize myself more as a client, but for me, it is more natural to see green machines as easy to win money with.
Finally, I don't know if it was only for my playthrough, but I was never able to have positive machine income, even though I got all cheaters. Is it normal, or am I just a very bad owner ? :p
