It's real 3D death chase! Yeah!
There are few problems:
1. If you die and respawn, the enemies will respawn,too.
2. Bullet can explode without hitting the enemies accidentally.
3. Somtimes, the tree hit box is strange.
Other than that, it is a really good clone! The graphic looks like the original game. Even the audio does. Also, good choice making the game 3D!
