Iphone retina display issue

Greetings there!

I have an issue here, that has been bugging me for long!

Now when you create a game for let's say iphone 4s or 5, with the retina display it gets 'zoomed' out, it looks smaller.

Does this mean that i need to draw everything in bigger before importing it under the retina display?

Or can i keep my drawings exactly the same size?

Let's say i draw a character at 150x150 pixels. Now when it's on the iphone can i keep it the same size or MUST it shrink since the retina display shows everything smaller? More pixels per pixel.

Thanks for your time, hope you understand me.

I believe I saw an option in construct 2 project settings to turn the retina display settings on or off.

Greetings there! Can it be turned off for certain drawings only? Or must it be for the entire project? Thanks in advance.

Just use a fullscreen mode like 'letterbox scale', and it will scale the game back up to look correct.
