I was very disappointed that after the difficulty level peak, it went right back down again. The last level was extremely easy compared to the previous ones. 19 by far took me the longest to figure out, and yet I got 20 the first try. I like the tactical approach to this genre, I thought I would get bored after the first few levels after playing many games like it, but the ability to reinforce and the thinking involved sets it apart.
Were there to be a sequel, either upgrades or a map editor would make this game superb.
4/5
Might want to try using something else besides arrow keys. Windows only allows you to press two arrow keys and all other input is ignored, so if I try to move both characters to the left or right and jump, the W and A/D are ignored and the arrow keys take priority.
You should really be able to kill the guards if you touch them. Often the waiting game gets very annoying and boring. If you could kill guards, it would add strategy so long as they aren't easy to kill. I stealthed and then popped out once they were close enough and was disappointed that I was the one who died.
With so many bugs, a non-uniform art style, and a boring game mechanic, there really is no hope for this game. As for the theme, you can't tell me that there isn't another way to set this up so that it doesn't seem racist. Go back to the drawing board.
I cleared all of the levels and found each one's increasing difficulty to provide a very good sense of progression. Each of the towers were unique and provided a good variety of strategies for different positions on the track. My only suggestions would be to provide an endless wave mode, and provide a better way to use the powers other than money because I never found a reason to waste $200 on something that could be better spent on an upgrade or a new tower.
Didn't feel like Shadow of Colossus to me for the lack of combat and the climbing was heavily based on platforming; however, for a platformer it did its part. Maybe for a sequel, make the player have to hit multiple points, so it not only makes more sense when they die, it'll be a little closer to Shadow of Colossus. 4/5
