Hello there,
I am core Actionscript 3.0 programmer. Please take a look at my reviews and feedback, I am one of the valued programmers in Actionscript here in Freelancer.
Regarding the project, the game is really nice and simple. Thank you for providing a background. But do you know this game involves physics engine as well. I have estimated the game to be maximum of 3 hours. My actual rate is $35 per hou,r but since your budget is very low, I have lowered to $25 per hour. An extra $10 is Freelancer's fee.
Let me know, if you are interested in my bid.
Regards
