Game is incorrectly labeled. it is only a Windows build (it will not run natively on any of the other flagged OSes).

there was some visual confusion in that some objects that were dangerous and some that were checkpoints both looked almost exactly the same.
The time mechanic seems to be to force triggers of the checkpoint/etc system… some of the paths needed to be taken seem way to long for the time given.
