I must say I have spent hours on this game, and now, after I've finally manged to get 3 diamond stars on all the levels, and also got all the achievements, I can finally get to reviewing.
First of all, the resemblences to Ironhide's "Kingdom rush" are so many and obvious, that not comparing the two games would be just silly, so I am going to compare them. First, and least important of all, you guys could have come up with your own map theme, just copying the one from KR is kind of a faux pas IMO. Apart from that, the content is very well made, maybe not as detailed and unique as what we see in KR but hey, this game is not about content at all. When it comes to gameplay and game design, well, it is excellet yes, but the thing is it could have been even better, and this really shows once you start playing for the diamond stars. At this point the skeletons become useless, and so the game becomes far less diverse as the player is down to only 2 types of buildings. At the very last few levels I ended up using only 2 types of final tier buildings with no special abilities at all, which was kind of boring.
Ok, that was the 'fail' part. Now for the 'win' part. And lets face it, this game is deffinetly a winner. First of all let me say that all the people saying this is a KR rip-off are utterly wrong. Yes the game draws from most of the ideas that came with Ironhide's game, but instead of just cpoying them, the guys at Storm Aligator did a wonderfull job of extending some, and attacking others from a completely different angle. I love the fact that the player is able to (hypothetically) build his towers anywhere on the map, i also love the "supplement" towers, and the fact that SA didnt just go for carbon copies of the towers in KR, but instead balanced out their own system. Difficulty is another strong part of the game, the diamond challenges IMO are extremely difficult, on like level 20 some of them seem utterly impossible, and yet, it all can be done. One more thing though, personally after completing all the missions for the bronze stars I went straight to diamond, and I do think that these 2 difficulty levels would have been enough. However, having the difficulty levels in between is by no means a fault.
All this said, this game is BIG, deffinetly equal in playability and a worthy successor to "Kingdom rush", and the fact that it was made by just 2 (!) guys make it a brilliant game. I would not be supprised at all to see Ironhide draw from some of innovations in DvF this time, if they ever make a sequel to thier game. The half star that's missing is actually because, if designed just a tiny little bit better, this game could have actually been better than KR.
