About Topload
You control a hand cart with a left and right slider. A crane is placing a box above your workspace. It is releasing it and you have to catch the falling box with your hand cart. Suddenly the next box is arriving from the top at another place. Move the wagon and catch it! Your stack of boxes is growing and growing and is getting instable. How many boxes can you catch with your hand cart?
Topload is a nice and small casual game designed using Googles Material Design.
And it is free at all.
