Think of it like this. If you make a Toss the Turtle sequel, not only will you make money from that flash, I bet there'll be renewed interest to play the first one again, earning you more money ;)
But I hope everything works well for you in the future!

If you really like flash games and newgrounds as a medium then I say don't give up! You just need to find a regular programmer who is reliable and move mountains together. I love your style and would hate to see it go.
