Pretty solid game, can be played both of keyboard+mouse or gamepad, personally I think the gamepad's gameplay is a lot harder.
The story is pretty linear, not enough branches but playing through it once is enough experience. Re-live the Jurassic Park movie in good graphics, it fills that emptiness of lacking dinosaur games in the recent years. I thoroughly enjoyed the hours I've spent playing this game.
Character development is alright, the player gets to make decision for pretty much everyone.
The game's fairly difficult in terms of reactive gameplay, it will definitely improve your reaction time and allows you to make clutch plays better in other games. I'd be surprised if anyone consistently scoring Gold throughout the game.
The game has interesting puzzles that you have to actually put into effort to solve (or trial and error if you prefer to not do the brain work at all)
A fair bit of jumpscares from time to time.
The only improvement I can think of is the continuity of dialogue/speech/action getting cut off/skipped and the accidental ESC press will bring you to the main menu with delay.
Overall it's another damn good game from Telltale. Worth it.
