Not a bad find the item game.
This game is fairly solid. However, there are serious issues that seemed more like "screw you" than it is fun.
The most glaring screwup is the fact that there are two "Draughts" in the last scene; a red draught, and an orange draught. If you're not playing easy mode, there's no way to tell which one you're supposed to click on. The next screwup is the fact that you also have a clickable object, "A Couple of Draughts". You could have mistaken that for a single draught. This isn't exclusive to the last scene either. I tried clicking on a couple blocks before I found "A Block" (I had to chuckle on that one, cause it literally had an 'A' on it). And then there item descriptions and a dozen similar objects to match (exaggeration). For example, when I first played the game, I was playing on normal mode, and kept on clicking on what I thought would be "A ball with a blue stripe". Sure, you could say I didn't read carefully, but then I had to choose between a ball that may possibly have a dark blue stripe, and a ball that may possibly have a cyan stripe. Eh?
There was another game I played a while back (I can't find it atm) that did exactly what you did, except different scenes and different objects. There was no confusion as to what objects I was looking for, even if they were sometimes hard to find. They were varied and unique, and there was no lame "yellow/blue/wine red/dark blue ball", just a "Ball", and there would only be one. I enjoyed that game much more than I enjoyed this one.
That's my two cents.
On the Sandbox level, the violet ball is labeled as "assetitem 2."
Otherwise, a standard example of the hidden object game.
very hard in hard mode
