I thought i've seen all about optimization after 7DRLs on Unity with ugly ascii chars being shown using modern shaders. But I was wrong. Now i've seen a 7DRL that takes more then 1 second per turn on (relatively old but still) core i7.
So while the name of the game and battle mechanics (and possibly squad mechanics, but i haven't got to it) are great, ii is impossible to have fun from it.
Any plans about post-7drl version which will work, like, 10 times faster?
