not professional enough
It's similar to what we've seen in the game called Shift, and the idea is okay, however, it really feels like a demo of the idea rather than a finished game. The movement is a bit choppy, it doesn't feel polished, and the level design is always very similar. The buttons and all are good, but that's it, there's no more to it. How about adding enemies and traps and stuff like that maybe...
Also, I feel the need to press shift all the time otherwise I have no idea where I am. I think it would be much better if the game didn't scroll at all, but rather you would be able to see the entire map at all times, with the player being tiny. It would make it much more logical.
