The game was quite fun, it's a bit slow at times but designing is quite fun.

It would be nice to have more space to build or use tighter lenses.

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.

So...........do you do this kind of engineering for a living? This is a lot of stuff and I can't believe you implemented so much in the jam timeframe!

I went in blind and was pretty confused as to what did what. I understood the basic concepts, but since the initial lights are so dim and sparse, you don't easily see the effects of your actions, including mirrors. After capping out around 1k W/s, I took a look at your screenshots. That was VERY helpful, and from there I could start to engineer my own designs. My suggest to you is to somehow make those early light rays easier to see. Might be tricky since that'll change the balance as well.

After that point, this game got very fun. I was enjoying tweaking setups to squeeze out more output. The upgrades just seemed to flow in readily because I was usually absorbed in the core gameplay to notice I could buy one. I haven't played a factory optimization puzzle like this before. You tackle new kinds of problems, like having "2 solar panels and 2 filters, how can you maximize this since it's hard to catch a lot of light with the filters?" 

In addition, the fact that you have limited space was a good decision. It really forces the player to figure out how to make this big chains of prisms and shifters without losing too much energy, whether it's due to the natural energy loss or trying to get the correct distance and angle on your concave lens. These are novel problems to solve.

I didn't expect to enjoy this one as much as I did. I'm not a huge fan of factory setup type games, but the addition of unique incremental mechanics really took this to the next level. Awesome job!

Great game.
I'm confused by the Xray tubes. The description mention xray require a special film to be seen, but is that something that can be built? Couldn't find it.   

I'm using them with the invisible rays, but I can't figure out how to rotate them. Is there an input and output side? Or does it just take UV from all sides and output xrays on all sides?

Tried to figure it out with a Detector but it seems to imply there's more xray the furthest I get from the tube, which is weird (and energy rate doesn't seem to agree with that if I put the panels further)

I just put a few Solar Panel randomly around it and I get energy but wondering if I'm wasting the majority of it.

cant build a light source. can build solar panel and detector but it wont let me build a light source. not sure if im missing something or its a bug.
