a good start
This is a good concept for a game, however I think you've made it way too easy. I expected to be following a long trail of clues and hidden evidence before tranquilising a fierce yeti and hauling it back to the lab, as opposed to it just appearing on the 3rd screen and it being so easy to take a photo of...
It was good that you included 4 different species to find, but it did get very repetitive. They could all be found on the 3rd-4th screen and weren't any challenge to capture. There's also a few spelling and grammar mistakes: the one that made me laugh was that you said the Lock Ness Monster could be Wales... Wales is a country! I can see it out of my window accross the Severn Estuary right now!
Annnyway:
Graphics: From the moment the game loaded up, i thought, "Wow, these graphics are great!" You really managed ot capture the scenery, and the close-up shots of the creatures looked quite good too.
Style: A good and unique idea, but way too easy and repetitive. As i've said, it could have done with having to follow a trail of clues, and taken longer than just 30 seconds...
Sound: Some nice themed music for each area. Maybe have grunting/rusling sounds indicating when you're near the creature? Makes it a little more exciting ;-)
Violence: A few battles to the death with the Yeti would have had me hooked... or at least being able to be hurt by the creatures.
Interactivity: You walk around (really slowly at that) and take a photo by pressing space... needs to be more in-depth with interactive environments and inventories and stuff...
Humour: I found it funny (in a bad way) how the animals were just THERE. Also Nessy looked funny ;-)
Overall: A good start, but could definitely be added to. Make it harder and last longer by setting out trails of clues. Maybe include more monsters such as Ogopogo and the Tasmanian Devil (google them). Your graphics are great. I voted a 3... good luck for the future, and i really hope to be able to play an improved version of this one day!
