Fun little game, pretty short and I also agree with Damian about feedback, animation and particle effects are really simple ways to make this work.
I wanted to get the idea executed first as I knew I would not have the whole week to work on it, hence I settled for only sound cues, but as have replied to Damian, making it visible that its a teleport would be a good change.
Yeah I completely understand the time constraint, no problem :)
