Thanks for playing and for feedback! Yeah, the game is meant to only take a couple minutes. It's mostly some of our game-breaking bugs that makes it difficult to progress through comfortably. It's a good idea to let players know how many levels there are, thank you!!
We originally had it so that the enemies can detect you from afar, but it was too far and messed with certain levels. We wanted the main character to feel more like a spy/assassin, allowing you to have greater vision over the enemy and kill the enemies safely. It may seem too easy with this, but the idea was to have more difficult positioned levels, so that you have to find ways to run behind the enemy in order to position safely and kill them. Too much to fit into one game jam sadly, but I am glad you had fun!
