Woah, I like this one a lot. The idea is so simple, but implemented so well, I could see myself playing more of this.
If I had to offer some feedback, it would be very helpful to have either a faster way to travel or some sort of enemy radar. I ran around the map 2-3 times trying to find the rest of the enemies, only to find one stuck in a wall. The bug is still need to be fixed, but at least it would be faster to find.
