I really hate to say it, but there a fair amount of aspects of the game that scream mobile. The only problem is that there is no way you would be able to control the game if it were on a mobile platform.
I am glad to support indie developers like Vlambeer, so I do not regret playing the full price. It just becomes difficult to fully recommend the game when I think that the price-point might be a little higher than it should be.
Maybe I haven't spent enough time with the game.
