While the puzzle design and general gameplay of Killer7 is extremely unconventional, a variety of in-game resources are available throughout each level to point the player in the right direction and provide assistance, key items, or upgrades throughout. While on the surface this may seem like it would simplify much of the actual experience, even these helpful entities are often obtuse or bizarre in their presentation, with what help they can provide often needing to be deciphered through context rather than used as out and out instructions.
