Algodoo

Great idea! (I should have thought of that).

I see you fixed the extra planets and missing planets glitch.

I noticed a couple of issues:

1. The score is not consistent. For example, the score updates when the first square of a pair is selected (is it supposed to do that?). Also, when the score is showing 0, it will deduct 6 points the first time a wrong pair is selected, then 5 points, then 4 points.... etc. I think it stops decrementing when the score goes down to 2. It's also inconsistent when a winning pair is selected.

2. When the HINT button is clicked more than once, the game freezes with all squares exposed and it will not recover until the Shuffle button is clicked.

Thanks.
1. I will look into this deeper. FYI, score := math.toInt(100.0 * sumOK / (16.0 + scene.my.clickCount - sumOK)), where sumOK is the sum of images (not wood) showing.
2. Fixed.

Understood.

More debug info.... I kept track of the score for wins and loses as follows:

Score begins at 0

First winning pair: +12 == 12
next winning pair: +13 == 25
next winning pair: +12 == 37
next winning pair: +13 == 50
next winning pair: +12 == 62
next winning pair: +13 == 75
First losing pair: -9 == 66
next losing pair: -6 == 60
next losing pair: -6 == 54
next losing pair: -4 == 50

So, you can see that adding and subtracting values for wins and losses is quite inconsistent.

Hope this helps.

The debug info is what I expect since it follows the function I listed above. The score increases when you get a pair right, decreases when you get a pair wrong, and finally shows the percentage of right guesses divided by the total number of clicks. I'm willing to change the function if you can think of a function that makes more sense. You also have the option of changing the function yourself and re-posting the scene. You could also add a time box so people could brag about the fastest solution.

Yes, I was planning on making some of my own enhancements too, but my time is limited until after the holiday. My wife doesn't see the importance of Algodoo like I do!

best i got was 35 on hard

That puts you on the top and bottom of the winner list.
