By not having a level cap, I would have to make much more content to suit post-late-game characters. That may be feasible down the road, but I'm having trouble balancing even a finite and incomplete game at the moment. If this were more than an after-work project, I would definitely consider it, but that's not the case. I wish I could cater to every play style, and every kind of person drawn to Axu, but the unfortunate reality is that I cannot.
I do like the idea of increasing the strength of body parts, but I don't want to have players get too cozy with a set of limbs, and never experimenting with other body configurations. It's a very precarious balance I still haven't worked out.
