Interesting concept, but clunky in execution. Upgrade icons are scattered across the screen, it's difficult to tell where you can place machines, and in general is just rather fiddly to play.
A suggestion to improve hub fleets, queues, and auto-routes. If there are buildings in a world's queue, and that world produces resources needed for their construction, reserve enough resources to build those buildings. IE, if I need 50,000 plastic to build a factory, and the world produces plastic, don't ship any plastic until there is a minimum of 50,000 at that world.
The icons for the snowflakes should be a darker shade of their color when you don't have enough currency to buy however many upgrades you have it set to.
Challenge 8 has a display problem when you Sacrifice. It displays the same values for all dimensions until you buy them again, when in reality everything except tickspeed is reset.
Game loses save? Okay, I backed it up manually, but I shouldn't need to. Not getting my offline bonus time despite having been offline for a few hours because of this? That's a nuisance, and I hope that the developers address both of these problems.
When I bought another "Free 10 Levels" talent, it broke the Auto-Rebirth. Now I have to rebirth to get the effects of talents. Or did this happen because I unlocked the inventory? I'm not sure.
Is there any particular reason for the rebirth mechanic to exist once you've maxed out the combo tree and bought the Save Experience talent? You lose nothing in a rebirth at that point, so why wouldn't you rebirth as soon as you bought a new talent?
Some minor things I'd like to see: A way to shuffle the antiparticle board, an indicator of how many omega particles and multiplier you're getting per second/minute/hour/day/whatever, remember the battle time multiplier between loads, and when you leave the follower/battle pages, have the button return you to the page you were last on. Add a separate button that shows up when you can claim followers, because it's hard to tell when they're available with the current icon. I'd also like to see a tighter connection between the two part of the game (idle and battle) and improvements to gambling and antiparticle to make them minigames in their own right. On the whole, this is a fairly good idle game.
These tournament entry fees are silly. 200 universe marbles to enter one? I've only ever gotten 90 free ones so far. Why would I spend real money getting more when I don't know how likely it is I'd see a return?
@raven0ak: It's not the same thing. Improved Next At keeps clones on the same skill until the next one is unlocked. My suggestion is for when the next skill is already unlocked and the current skill has more clones than it needs to cap the skill.
