The layout confused me for a second, but other than that, I really like this! I guess I would like things like HP and battle damage clarified, since you did mention turn-based combat. Resistance was described as similar to HP, but it seems to only apply to obstacles.
Thank you so much for your feedback! My apologies for being *slow* on the reply. This project was somehow thrown on the bottom of my todo list.
The layout was inspired by GURPS one page, which I thought was really clever how they used space. If I were to continue development of the system, things definitely need to be re-thought out to make it easier to understand.
Version 0.1 of this doc was I think 27 pages if I remember correctly. I squeezed it into 1 page over 2 days. I actually really like this system but I think I got overwhelmed with the project after that.
If you still have interest, please let me know and may be I will get back to it :)
Thanks!
edit: looking now to try to find the GURPS one page I was talking about. Seems I can't find it, so I may be mistaken. The game I was talking about is folded the same, and the density of the page is similar. Perhaps it was a fan remake or a different game entirely.
