Given the incredible simplicity of what you were trying to accomplish it is amazing you managed to fail, let alone managed to publish it without realising.
The hit detection in the defender level is possibly the worst I have ever seen. Stupid children have made far better systems. In the spikes level sometimes the gaps are much further apart than you can run in the time, (even if you went off the edge) and one time spikes without a gap came up along the whole level and killed me! Utter, utter shit, 0/5.

This could be very good, but its just too buggy at the moment. There are a large number of interface issues to be cleared up as well as gameplay ones. On the second level I took 5 guys, and they were all killed by the first wave of demons. I allocated lots of reseach in the first level but still couldnt get any upgrades.
