Level Test is a Keen 1 level pack released by Xky Rauh on Keen Day 2008. The included level was used as part of an experiment. Community members were asked to record a video of their play with DOSBox and upload it to the CKFS. Xky's intention was to analyze the behavior and play style of the participants when exploring an unknown level. Nearly two weeks after Keen Day, he posted the results. Additionally, CK Guy uploaded the videos to Dailymotion.
A sign at the start of the level instructs the player to press Ctrl+Alt+F5 in order to start video capturing. The level features multiple paths and long drops. There are no sprites besides Keen himself and it is impossible to die, but the testers were initially unaware of this. The aforementioned sign reappears left to the exit door. The door can't actually be entered, the game is intended to end as soon as the video is finished by pressing the same keys again.
The level pack also contains a very simple placeholder level that cannot be reached without cheats. Keen only has to enter the exit door next to him in it.
