Tried out the demo. Few specific issues:
1) Took 30 seconds for the game to launch. I had thought it had frozen for a good while and was about to check Task Manager, when it suddenly opened.
2) The interface started out in... German, I think. Took a few minutes to find a button that would allow me to change to English. After doing so, some parts of the UI are still in German.
3) Told, on the first screen, I have "click power". Click on what though? Nothing I clicked on generated any energy.
4) Earning energy, not sure what to do with it. Hit some upgrades, doesn't do much, but does consume a lot of energy.
5) Have no idea what I'm doing. The interface isn't exactly clear on what I'm attempting to achieve. Or what my action clicks are doing to the gameplay. UI feedback and general navigation is poor.
6) Earned a skill point. Looked at skill tree. Read several skills thoroughly. Still have no idea what they do.
7) Fiddled around for about 5 minutes, and gave up.

Hope some of this is useful to you. Appears its a bit too complex an idle for me, so not likely my cup of tea. Which is fine; just means I'm not your target audience.
