First of all if somebody enjoyed my game - please check out Yellow's submission too!
Now to the point:
Movement system is made this way because a) it was quicker to code and b) I had different idea at first for which it was designed and there was not enough time to redo it completly.
In defense of the system - I think precise movement prevents from frustration when you go too Far without a way of going back. But if I will ever improve the game I'll try to make it possible to switch between "Tap to move" and "free roam" so everyone will be able to choose what suits them.
Thanks for your comment, glad you liked it.
