Great so far, I noticed some reviews mention the requirement for string 3 being too high but that was fine...string four however does not seem possible. The abyss looks fun but I cannot begin to understand it. As far as I can see the only thing you can do is wait and upgrade when possible. Hopefully it will speed up a bit but after a full day watching it, it's still pretty slow.

Overall great though, and I know it's a work in progress so I'm judging it as such.
