Interesting concept, needs some serious work.
Alright, aside from the 'click-and-drag-shapes' sort of graphics, and music that is putting me to sleep, the controlling needs some work. There is no accuracy, which players would need in an environment littered with targets. It's also difficult to slow down at times, causing your character to bounce around aimlessly when you try to catch that little house on the far side of the screen.
That said, perhaps figure out a different method of spawning houses? When I clicked 'play', it instantly purchased a house that had spawned right where the character was standing. There were numerous times when I was moving towards a house I wanted to buy, and suddenly the 'purchased for $$$' sign comes up, because a house spawned right on top of me. Or it spawned right in front of me, but I cant stop because there is no accuracy in the movements. You just.. keep going.
I do like the concept though, and at least it's otherwise running smoothly. I would love to play this after it's been worked on a bit.
