I loved the graphics and the sound effects, also the introduction animation with story and so.
However, I actually didn't manage to find how to get over the first spikes ground, as jumping over the bricks didn't work and I found no other input control or trick to move ahead. I just kept falling on the spikes and dying. If that was the intention, ok, but that's not fun :D
Anyways, given the graphics and audio, I guess it's a good achievement for 1 week work :)
