WASD or arrow keys to move. Press 1 to use spray, press 2 to use water bomb (has cooldown). Green flag to restart.
Excellent graphics and fluidity 
Far too easy in spray mode - even I couldn't lose
I think person should turn to face left/right when pointing left/right with gun
Ty. How would I detect if the mouse is to the right or the left of the player? 
Well the gun points towards the mouse so the direction of the gun should give you enough info to work out which way to face
That's a cool game ! Thank's for sharing it !
I like it! I rate it 8/10.
I agree with cymplecy that spray mode is a bit too easy. I have a suggestion: Make it so that the flames come faster and/or more of them appear as the game progresses.
Nice game. This could also work with the new tilt sensors so you could play it on a tablet.
Or a cooldown on the spray?
7/10. But only if you use water bubble mode. I like how the water bubble "bubbles". Spray mode makes it so you can just spin the sprayer and it is impossible to lose. The water bubble mode can be a bit challenging at times especially when you have to reload and the flames are on opposite sides of you. It would be cool if the flames got faster/spawned more as the game progresses.
