Yes at the moment there is only one level. If you collect pieces of evidence AND complete the level you get to inspect the items in the player apartment for some background story. Also if you do a "true" level competition (meaning you collect all 3 pieces of evidence and complete the level in the same run) you also get a slightly different end Screen that also gives a little bit more story. I plan to expand the game in the future so feel free to follow to keep up with it :D Glad you enjoy it!
