Bottom line on this game is I did not enjoy it and don't think it is worth even the 15 minutes it took for me to die twice. You play an employee of a dinosaur park (a Jurassic Park knock-off which is ubiquitous in the game world) on the day when another employee goes crazy and opens all the cages. You have to escape from the park somehow.
I just didn't care about any of it, not the characters, not the "puzzles", not the writing. If you die (no real way to tell that's what your choices will lead to) the game will let you restore from the point where it all went wrong. I died twice and restored, trying a new path, but before I even got to my third death (or perhaps victory) I got bored and quit playing.
