Level Up
These exploding boxes come with an audible "BOOM" with every level up. It's not too loud to be distracting, but it's certainly noticeable
Life loss
A red vignette and an Inception-inspired VROOM noise tell you when you've messed up, in case the block flying at your face isn't a good enough clue.
Slow Motion
A deep blue vignette and a wonderful sound effect of slowing all playing sounds happens when you hit the slow motion button. I love doing it as a block passes by, the WHOOSH sound is awesome slowed right down.
So what do you think now you've seen the vignette in action? Too much? Too bold?
