I thought about making a game like this a while ago but didn’t get very far. Your version has a lot more features then mine ever did. I enjoyed playing it except 3 levels was not enough (can the non trial version your going to release be free? ). I think it would do very if it were submitted to Shockwave.com.
I’m not sure about ‘monetization’ for now.
Idea is to make a free and full versions. If we can make a deal with shockwave - great. If not, wooglie can be a proper place I think.
