Is there a recommended limit to instance variables?

Quick question. The number of variables I have in my 'Enemies' Family has just reached the 20 mark on 26 different Sprite objects, and I was just wondering if I was pushing it. There's only one text variable, by the way.

Should be fine mate.

Good practice in general though is to always have a look in debugger after implementing new features for your games. Clicking on the profile tab will give you a good idea of how things are going.

Will do. Thanks.
