The music loop restarts before it has finished, leading to an excruciating cacophony of noise. Combined with the annoying colour-changing background, lack of a next-piece indicator and faulty API, I am left wondering why you bothered.
If you are struggling, turn up the quality settings to max, this will make the game run very slowly. I went from a best of 100,000 to getting bored at 5.2 million on dimension 13.
Look here, I can understand that the FIRST time a level loads, it might take a bit of time on my creaky old machine. But why does it take so long to load after I die? Surely the damn thing is already in memory? 20 seconds of load time per death is just rubbish, sort it out.
funny glitch: select the motor tool, then click rapidly on a block that cannot move freely. it goes mad and spins round the screen, before removing itself from play.
