Working with global variables is covered in the manual and the tutorials. I would highly advise going through them. The proposition here is to create a global variable for each of your acheivements. Define what has to be done to get each acheivement, then when the task has been accomplished, set the variable. Have code that reacts to the variable. You can then use something like the web storage object to save that info between game plays so the player still has their achievements. So here are the things to look at in the tutorials and manual:

Global Variables

Events and Conditions

Web Storage

That should give you enough to impliment it, you just have to come up with the actual logic and requirements of each acheivement.

You should be able to get somewhat closer using damping, etc... but not sure if you will be able to easily get the same realistic rolling reactivity that you would with physics...

Look through the tutorials at the samples there, look for the ones on rotary style games, while your whole game may not be using the rotary type movement, it sounds like some parts at least will be. Also read the manual. 99% of basic questions can be answered between the tutorials and the manual.

On a side note, you should use something like skydrive as your default save location instead of a local save. With skydrive you will have your project safe no matter what happens on your PC. Same for box.net, etc... save often to your sync folder and you don't have to worry. Also as suggested, Windows has been stable for a long time... if you are still using XP, then you are inviting disaster by choice anyway...

Hello There, please update the title of this post to have [Solved] at the beginning so other who may have a similar issue can more easily see it as useful.

I would look through the tutorials on scrolling, especially the paralax scrolling or endless jumping/climbing tutorials. Same logic, only have the scrolling go the opposite way. The Manual and Tutorials will answer about 99% of the basic questions you will have.

It would work with a combo box that allowed the list plus user created entries to support the variable options...

Gilden I am most likely going to pick this pack up in the next month or so, I wanted to see what the graphics count is at, and what additions have been made since you went live?

Is there an event for on focus lost? May want to put some type of pause action whenever the game loses focus with a message telling them to click/touch in the game area to continue...

You should be able to publish to scirra arcade just fine, you can put the game other places too, as long as it is not being sold for money. That would require a personal or business license...

You can export your game as HTML 5, then just copy the folder (making sure to include the Index.html file) zip it up and send it to your friend. It should work fine. Just open index.html and you can play the game.

For licensing you need to read the licensing info article. I would highly recomend reading the manual and the tutorials as 99% of your questions will be answered there. Here is the link to the licensing info:
