I thought this was written in java. Is it in c/c++ then? Kind of impressive how small the files are for the game. the performance is flawless, truly this is one of the few DD56 games that runs very well on my system, congrats on that.
good idea to put keybinds in the pause screen
itd be good if enemies seeing you could be blocked by level terrain and they think you are where they last saw you before being blocked. that way you could double around behind them and see their backs and that'd be nice.
a gamma/brightness slider for the graphics would be nice.
its nice that the guys "pick an angle" and fire on it even after you move, helps make the spike be very useful
