Hi, thanks for the feedback!
I've set the goal to business license because the minimum campaign I can run on Indiegogo is 500$. I want to set a flexible funding campaign because as you say the Personal License is enough for now. But if the full goal is reached I think the Scirra team deserves all of it for what they've accomplished. I really want to see this community grow and succeed.
As for the unfair part I will try tweaking enemy positionning to make it better and I will experiment with enemy stomping mechanics to see if it works well for the game.
