This has gotten worse as this developer has updated the game. It's not difficult or challenging because it's realistic, which should be the case, it's difficult because your troops are absolute morons, take minutes to line up a 12 yard shot, and they can't seem to manage to hit anything. This has so much potential in the amount of detail that has been put into it, but it is absolutely crippled by the logistics.
This is not a good game, but it is an excellent interactive story. You did very well with this, the multiple paths with multiple explanations that tried to immerse the player into the story were very good ideas. The shortcuts to each part with the selection of traits and behaviors was a very good idea, it took away a possible source of frustration. I can't say that I like the graphics, I see a lot of games that look retro like that, and I don't know if it is a great idea. But you utilized them very well, and showed a lot of detail and character in a simple manner, and it gives the game a bit of charm on top.
This is terribly frustrating. The levels aren't inventive, they're just annoying. This and the laggy controls makes for a crummy game. What am I working for again? The levels don't get any cooler as I go on, they just have more spikes, I don't find any reason to progress past the first few levels.
