I like it but its frustrating

I like the game but to me its a little frustrating. The first level requires you to stack for 60 seconds. I have a hard time stacking past 12 crates. Which is usually only 23 seconds into it leaving 37 remaining. So I have no idea what happens when you reach the 60 second goal. It also needs a menu with other info, quick and easy to make and would make it feel more developed. Anyway its worth checking out.
