ok, i really like this
you've made an excellent game here. the controls are extremely simple, the gameplay is pretty intense, though I admit it can get a little tedious. your graphics are superb. if you made a sequel to this, i'd like to see something like grenades, mortars or firebombs added to the arsenal. An upgrade system would be interesting, but i hardly think it's necessary to improve the game. as it is, you've done an outstanding job. congratulations!
