bother me a few little things

A nice game in which the objective is to prove himself as a bridge construction workers. What I lack is a tutorial where I will once informed about the technical possibilities. A few notes there are of course in the first level, but only in the context of the game itself. The task in each level is to build a bridge. There are requirements to use only a certain amount of "money". But somehow the skin out already not. Because even in Task 1 should not spend more than 3500 - but even with the instructions of the program you have to spend 4500 - otherwise you can not build the bridge! But if the cheapest option of the bridge already 4500 costs - how can there 3500 issue as the program objective? This is totally unrealistic and spoiled a somewhat the fun of it. When I build the cheapest and proposed variant of the bridge, thereby overstepping the maximum allowable use money, which for me is already built-in bullshit.
The parts of the bridge are assembled with the mouse. One has to always complete the construction phase with the right mouse button - but at the same time to delete with the right mouse button again, the vornagegenagene action. Until one has worked there a few nerves are already blank. Again, the lack of a tutorial is noticeable.
Otherwise, the idea of ​​the game is very good. You have to either build bridges that can withstand a lot that goes up to the attack by the enemy, or you have to build bridges that collapse, when the opponent is on the bridge in the middle - if they collapse prematurely, the opponent can not save. If they collapse too late or not at all you have also lost. The interline interval is a nice challenge, because you have to try some of them very long.
A little awkward is the presentation - all instructions are given partially in long texts. There is no option to listen to that. For some players, the problems likely to prepare. After four weeks of practice I am still not by the way - which is however certainly on my limited technical skills. It's fun in the end.
