The game is really easy to control the player, it is good using for it. The greybox here also not bad. I am looking forwards your further developing.
However, there are also some problems here very bad effect on UX. The size of player is much bigger that the house, for users it is imposible for our expirence. Not only that, the ground is so boring, no more features in the ground. So you can put it more perfect decoration, that may can improve your UX.
