This looks really cool. I really like that you can recognise the rooms even with such minimal character art. Is this going to be crime solving game?

Yes and no. It’s more like a crime “discovery” game. The crime gets solved whether you do so intentionally or not, but whether or not you’ve got any idea what’s going on is dependent on whether you looked at the clues. The more clues you find, the more of the plot is revealed to you.
