Looks solid, congratulations

Very good indeed. The video looks great. Is it from scratch or did you start from an existing project?

About collisions, I choosed the simple way. I resolve them by rotating the velocity vector from an angle of 90°, while reducing this vector (the x-component at alpha percent of its own value). That is not how it works. Take a look at the first case on the image. A low throw causes the ball to jump ...

I edit the code in a simple text editor with highlighing, and to try it I go to "main.lua" tab and press F5. For me it's the faster way to work.

I'm sorry but I have no idea what you are asking. Try to explain it more detailed, please.

Anyway, great job, the aesthetic is really cool and the gameplay is really smooth
