pretty cool idea - i got stuck near the beginning where you get to the first door you need to open.. i could get both guns to fire so a button would click but the door wouldnt come open.. i tried both buttons.. maybe im just doing something wrong im not sure

i mean i think the point is that your supposed to combine the guns to break the shield of each button right? well - when i would shoot the button would just toggle on and off very quickly

I like it very much. The arena and the controls combine into a sort of action puzzle. EarthBanana: I know the Ghostbusters have their rules, but man, you gotta cross the streams.

Even in this short demo, I saw a lot of variety in the fights. Sometimes you're just testing your mettle, whipping the targeting reticle around the screen to plow through hostile targets. Sometimes you're maneuvering around threats like in a bullet hell shooter. Sometimes it's an obstacle course. Sometimes you're using the turret positions and your game piece to make patterns that solve problems. You have time pressure when the red zones expand and a short HP bar and some enemies are shielded but the weapons always feel powerful and every time I lose I'm sure it's my fault and I could do better.

I really like what you have going on. Add in a leaderboard and some fancy graphics and maybe a couple different turret types and I'd pay real dollars to play this game.

• Very nice particle effects!
• I somehow ran out of ammo but had no instructions on how to reload. Perhaps a UI-layer with instructions and ammo/weapon info would be useful.
• Runs smoothly, does use computer resources efficiently.
• No objective information (should be added in the UI-layer.
• Nice sound effects
• What are the interesting shapes doing inside the walls? http://snag.gy/2fwM4.jpg
• The weapon does not fire from the tip of the player-triangle. Its somehow cutting from the sides in a strange manner.
• Sometimes I can fire and sometimes I can't. I guess I have to have a blue box within the circle, but there is no info confirming this.
• Some tutorial info in-game would be good (in the first room).
• Adding an extra ui-layer as a div can interfere with the libraries you are using to collect click events for the game. (My experience). Building the UI elements directly into the engine could be better.
• The second gate (with the dual buttons) won't work for me.
• A flare/shift of color that indicates source of fire would be a good visual que. You can for an example change the blocks that fire from light blue to dark blue or something.

I tried it out, using IE (I know most people use other browsers, but you should always try to be a cross browser compatible as possible)

There are only a few little things that I noticed

1) When loading the resources, after pressing the 'Play' button, it sort of just 'hangs' , at first I thought my window locked up, but then the game started, so, maybe a 'loading' screen or progress bar would help to show that it didnt just lock

2) The screen will scroll smooth most of the time with the player, but on occasion the screen will shake, almost like there is an earthquake happening. Not sure if you are doing that on purpose?!?! If you are... cool, but if not, might want to check out your screen movement (camera movement) code.

I really think you have a cool idea, and I see lots of potential here. Good job XD
