I meant same as you would push the magical red x and start playing again from the beginning. There's just too many variables to set them all to original values at the "Game Over press space to continue".
Ah, I see.
Well, currently that's the only way to do it, unfortunately.
Actually... I suppose you could Quicksave at the beginning of your game when it first starts up, then use Quickload to return to that state. I haven't used Construct's built-in save features much, but as I understand it it's akin to a save state for an emulator. I think.
If your game is big on memory resources you could save/load from disk. I don't imagine it would take too much time to restore. You could hide the load time with a fade transition or something to a blank, black layout if it's got a noticeable lag.
