good

the enemies did the same thing, so it was really easy to kill them, I made it to around 40 some kills before I got bored

perhaps make the enemies a little more strategic
hp regen is a biggie
the ground kept disappearing on me

however, you made this from scratch...
which is pretty freaking impressive...
for that
4/5

Things you need:
A cross hair.
Be able to move from 1st person to third.
Be able to upgrade.

Things that need to be fixed:
The land kept disappearing.
Add a sky.

Other then that it was rather boring.

I cannot stop spinning

display of 3-d graphics programming. Far better than I could even fathom to understand right now. And extra bonus points for resembling my old lover "Quake 3 Arena Demo" :)

The control was very frustrating. It should be tightened up quite a bit.
Maybe some levels? First kill 10 (choose a weapon), then 20 (choose another weapon), then 50 (choose a third) etc. If you were to go this route, a way to heal should be included.

Anyway, as much as I feel this game is lacking, I still feel obligated to beat my score of 35. Go make an update!!!
