Created an itch account just so I could leave this comment. Started playing this in the morning. Suddenly it's 6 hours later and I'm still going. Barely stopped for anything. Good fun! An excellent puzzle idea. Simple enough UI. Like some, the x-rays were a bit confusing at first but a little experimentation and I figured it out. It's just a little unfortunate that my most efficient design by far proved to be amongst the simplest I could make. Not sure if I was going about it wrong or not, but still it was fun to try out different methods.
Anyway, here's my final build! Tried a few things to increase the energy gathering but I couldn't make it any more efficient. Didn't quite make it to gamma rays. But that'd just be a matter of waiting a bit.
