Just to give you an idea of why I wasn't interested in the game, first of all there's the Jack of All Trades issue. It just can't be done, certainly not with a tiny team. 3d games require lavish effects and models and compete against all other 3d games out there. This has been mentioned already on this thread.
But here's another aspect. I never wanted to play as a Raptor. But I could easily get into that fantasy, if it was fully fleshed out. Imagine a game where you can play as a Raptor. You have your pack, and maybe you start off as a baby Raptor, some members of your pack die, and eventually you can be the alpha male, or you can leave and be a lone wolf. You'd have random procedural adventures in the ancient savanna, or maybe have to survive as long as you can in the extinction phase (kinda like a zombie simulator for dinosaurs), and you could definitely try to take down a T-Rex. The animal survival genre is horribly underserved (anyone remember Lion or Wolf?). I could totally buy into this fantasy, and I believe many others could as well.
However, placing the Raptor in a building, and making the opponents robots... well, that's like taking a swashbuckling pirate and placing him on Mars. It breaks any notion of the fantasy we might have in our head and just seems random. The Raptor in this game could be any avatar fighting robots. In fact, if the plan was to not make this a mindless action game, a more vulnerable avatar would probably have been preferable (something akin to Abe from Abe's Oddyssey). To see the power of tapping into a coherent fantasy, just see the recent controversy with No Man's Sky.
Developers break players' narrative expectations at their own peril. Sure, you can come up with a complex narrative explaining the particulars of any situation, but you lose the passion and narrative flow that players already have. If your game follows expectations, players will supplement the narrative with their own personal stories.
