Build me a simple 2D sandbox with physics based rules

Job ID: 34270242

Budget: $10 – $200 AUD

Hi, I was wondering if someone could build me a simple 2D sandbox with physics based rules.

I just want to have simple objects like circles etc. that I can drop on the page and set parameters for gravity, bounciness, speed etc. I would like it for use on a PC with windows.

I am probably really oversimplifying this in my description so I'm sorry but I have no idea about these things. I am pretty good at figuring things out myself so could you supply a really simple tutorial in text form of how to add to the source code or the back end so I can add and improve it over time.

I have no idea about the standard cost of something like this so please let me know how much your time is worth and we can work something out.

Thank you in advance.
