Neat, but went by a little too quick. My first universe was basically just the tutorial, but I still made my way into the next universe with a fair chunk of resources. On my second, I cleared two milestones to get as far as Fission. With prefabrication, I was able to take a bunch of productivity buildings and fission plants into the third universe, in which I won the game. I didn't even need any of the time-expanding techs, I had like five minutes to spare before taking the tech that abolished the time limit.
Related, Dyson+ feels pretty unfinished. In particular, the fact that there are upgrades more expensive than "win the game" seems odd. It'd be okay to ask for something unreasonable here. The player has so many tools to build up a huge economy, big numbers are just kind of a given in this sort of game. It wouldn't at all be strange to make Dyson Spheres and later tech stuff really expensive.
In QoL terms, I'd have appreciated buttons for drone control other than the x1, x5, and xALL you provided. Maybe a toggle button somewhere for how many drones to retask at a time, that let you switch that intermediate between x5, x10, x25, and x100? More automation options would also be nice, maybe something like 'auto-reassign idle drones to cover resource shortfalls'?
Also, I generally found that (with everything toggled on) hauler drones would waste time hauling stone and coal and such while ignoring high-tier resources. It's not that there wasn't enough space to hold it, there was just too much low-tier resources to haul it all in. Ideally, I'd want drones to haul a little of everything, but if they're working down a list, they could at least start at the valuable and difficult end of the list instead of the cheap and bulky end?
