I just checked the game out. I liked the mall exploration aspect a lot.
For the tutorial in the beginning when you are showing the keys that need to be used, you show an up arrow on the keyboard button. That isn't very accurate, as for my keyboard, the up arrow is on the d-pad. the Shift key has no arrow on it, and only says Shift. so maybe fix that so it says hold "shift" to run, instead of just the arrow for shift?
I also noticed some screen tearing when I was playing, will you add v-sync to the game later on to help that?
