Great game. Longer than most of the other games in this Jam, yet shorter than most of the famous incrementals.
I noticed that the radio telescopes, and the Dyson sphere energy generation, are pretty much useless. At first they're weaker than a maxed-out Solar Panel; later on they get upgrades to be slightly stronger than a maxed-out solar panel, at the cost of being vastly more expensive. I recommend multiplying the energy capacity of all radio telescopes by 4, and slowing down the cost progression for upgrades. Setting up the Dyson sphere is expensive enough; the radio telescopes don't need to be expensive too.
