It was fun and challenging. However the quiz at the end seemed random, and the game is super short so the challenge didn't last too long, especially the click and drag level that could have maybe had 1-2 more levels. Also, the music doesn't really fit, maybe it's just me but the music feels like it should be in a 2D detective game staged in the 70s, not in this. Also, add border walls, it's really annoying how when the block goes off-screen I have to reset (someone else mentioned the window moving up and down with the keys so I'll leave that out). Also, the title doesn't fit with the game so some people might be expecting something else when clicking on this.
It's a great game/concept it just needs to have more stuff built on.
