It's okay. I finished it. Many issues. Many mechanics don't trigger enough to matter. The turrets and insight are pointless. Low tiers don't matter as soon as a higher tier is unlocked. The big issue is energy/sec. It's WAY off if the simulation's open. It says you're earning 5e20/s, but it's 10 times less or worse. To actually earn the amount it has to be in the background, which also disables the autobuyer. I'd leave the screen, wait a while, then go back and turn on autobuy. Tedious.

Just finished this and took me a couple weeks to get through it. It's one of the best Idle games I've played. I'd put it right up there with SPACEPLAN which is one of my favorites. The visuals are beautiful, the soundtrack is great. There's a couple times where I felt like progression really slowed down a bit, but overall it's absolutely excellent. I saw others reporting having issues/bugs, I personally experienced none during my playthrough. I hope to see future releases of this style!

Thanks, you might like some of our past releases too (similar style, particularly Force Escape, Mind Construct and Idle Drops)!

very unique and interesting integration of gameplay, puzzle and visual mechanics. unfortunately, the gameplay loop and progression mechanics are very weak. most of the time also, the puzzle like mechanics comes down to pressing the same button repeatdely which feels like a missed opportunity. being extra harsh with this one becuase i purchased it just to get bored after a couple of hours.
