You need to add the browser object to your project, and then call for the "request fullscreen" action in your event sheets.

Manual Entry for Browser object

I'd suggest doing the tutorials and reading through the manual. They do provide almost all the information you'll ever need to know to make just about any game.

You could use the car movement behavior in conjunction with the pathfinder behavior. Instead of moving the tank with the pathfinder behavior, just use it to find the path. Then use the car behavior to follow that path, and leave a condition saying that if the next node is closer to the front then go forward, or if closer to the back go backwards.

Not sure how to do it exactly in PS, but in Paint Shop Pro 9 you can create a mask layer by the image source's luminance. The darker the color the more transparent it becomes. You would probably then want to edit the mask so the orange sections aren't as transparent.

You mean like this?

Granted, that was only a 2 second job in PSP9 and needs a little touching up, but your image wouldn't work very well just doing the one black color because you'd end up with artifacts around the borders of the explosion images in each frame because of the aliasing/smoothing done around the images. Instead you'd go for a luminance mask, and then clean up the mask afterwards to give better color while not getting all that black outlining you'd normally get from just picking a color to be an alpha color. Unless that's the look you wanted to go for.

Construct 2 Arrays need the JSON files to be in a special format to load them as arrays. The format is

{
     "c2array":true,
     "size":[
          2,
          13,
          1
     ],
     "data":[
          [
              ?[1],
              ?[1],
              ?[4],
              ?["Name"],
              ?["null"],
              ?["URL"],
              ?[10],
              ?[0],
              ?["true"],
              ?["true"],
              ?[0],
              ?[1],
              ?[1]
          ],
          [
              ?[2],
              ?[1],
              ?[4],
              ?["Name"],
              ?["null"],
              ?["URL"],
              ?[15],
              ?[0],
              ?["true"],
              ?["true"],
              ?[0],
              ?[1],
              ?[1]
          ],          
     ]
}

Put the objects in a Family together. Then do a check for

distance(Instance.X, Instance.Y, Family.X, Family.Y)

I would also like to see the ability to set the default animation. It's easier to group certain elements together in one object, things like UIs or animated scenery.

Construct 2 is pretty much a strictly HTML5 game creation tool. Node-webkit is a wrapper. That said, it's an exe wrapper. Try it out, see if it's useful for your purposes.

If the user is on an Android phone or any touch device with a keyboard you should give the user an option to use touch or the keyboard. Have some sort of variable (either global or in an array) keep track of which input mode the game is in. If a key press event occurs, hide the controls and make them untouchable if they're hidden while enabling the keyboard controls. If a touch event occurs unhide the touch controls, disable keyboard events.

There's also a sprite property that you can change at edit time, at the bottom where you can also set the initial frame and initial visibility, in case you want it to start off with no collision detection.

If she has a 50/50 stake in earnings/ownership/etc..., she shouldn't be asking for payment from you for work she's already done. You're not her boss, she's not a contracted freelancer, you're partners.

RogueNoodle is right though. Come up with some sort of contract before things get sticky. You already seemed to agree to 50/50, be a good idea to get that signed in paper by the both of you.

As for the 2 members you're going to be recruiting, definitely get an agreement written in paper with them as well, with signatures.

I like using ResHack myself to modify exe icons.
