The artwork is absolutely awesome, I love the low poly style! The game was quite hard though, mostly because of the 3D perspective of it all. It was very hard to correctly line it up, particularly the holes on the edges of the screen. Perhaps the camera could have moved to stay behind the finger, so that you could clearly tell what lined up? Or maybe show the shadow of your finger directly under it so that you can judge it's position in 3D space?
The game looks really cool, but I couldn't get far, partially because of the perspective, but also cos I'm not sure what to do when there's two holes at once. I'm seriously impressed that you could make what you have in a day, I would've loved to see what you could have done with the full week!
