I believe it was mentioned that doing offline isn't currently supportable, but what is the limitation stopping it exactly? Other idle games have used various methods of offline and I think the most beneficial version for this kind of idler would be the "Bonus Ticks" which would effectively just increase the speed of gameplay for a time after spending a certain time period away. If you could access a system clock or perhaps a clock based off of something else, to avoid player shenanigans, it may be possible to create a temporary fix until the engine can support what you may have planned.
I like the click and learn method, but some hints would help. Like the fact that Mana is only useful once you win a few battles and get "Active" runes to cast with.
I wish we had a "test room" that we could set up small scale reactors in to see if design changes would explode a reactor before we install the change.
Most games like this get boring rather fast, I have been playing since before Endazu. I actually spent a few bucks on this game! I don't think I can physically quit anymore. This is an amazing game.
