Cool thanks for checking it out! All good ideas. Def will look into adding mouse zoom and pan movement, that would be nice. I could add to options menu to change speed preference, among other things.. I left out specifics of the energy gain, but menus say what the interaction is basically. I'd like to add a hover text with more details of energy amount gained. Def need to fix that small text. I'll probably add all the fixes to this one and then work on a new version. Getting lots of ideas for how to improve it and take the idea further. And spend more time on it too. Thanks!👍
