I somehow completely missed that it existed, now waiting for the public release along with the release for MoAR:Complete I'm really exited for the 3pp content coming out
When I was trying my hand at making characters I got really frustrated with the lack of space in some places of the Level Up character sheet, my solution? Making my own character sheet. It started relatively small with a generic sheet but soon grew into the project I'm currently working on...
I agree that a system similar to it but keeping initiative in some form would be nice, opportunity attacks are mentioned at some point tho: they can occur the moment a character leaves the space of an enemy and resolve before the character continues
also, have you ever taken a look at the simultaneous combat system?
I like that you keep initiative over the way they do resolution, but their movement seems a lot more streamlined
