I have this idea for a simple game, a photo-hunt/hidden-object type game.
A hidden object game (sometimes called hidden picture) is a genre of puzzle video game in which the player must find items from a list that are hidden within a picture.

So my first question would be how to actually achieve this. My initial thought is to separate the objects into individual files with a transparent background so that I can overlay them on the main scene. Does this seem correct? If so, how do I actually do the overlaying and subsequent removing of objects, I'm guessing I will need an engine, which leads me to...
My idea is to make it web-based, specifically looking at HTML5 so it's cross-platform. I first thought of doing it with canvas but then I stumbled upon this: https://developers.facebook.com/blog/post/2012/04/17/making-a-speedy-html5-game/, where they say how canvas was actually quite slow and unusable so they ended up with their own rendering engine. Are there any ready to use engines that could fit my needs?
Basically, I'm not to sure of the direction I need to take to make this. I would appreciate any and all tutorials or documentation or whatever kind of learning material :)
