So I'm soliciting your feedback, internet community, on Into the Depths (link is to pdf download). For those just tuning in, Into the Depths is a classless, attributeless retroclone that I wrote at the end of 2016 that incorporates most of my favourite houserules from years in OSR games. It should be compatible with almost any d20-lite ruleset (Swords and Wizardry, Microlite20, etc.). I spent 2017 playtesting it, and I have some ideas for new material for an upcoming revision, but I thought I'd ask you, the wider old-school D&D community, to take a look at it and collect your feedback.
I'm particularly interested in any parts you think need clarification, expansion, or simplification in the rules as written.
Here's a link to some of the changes I'm planning to make based on my own playtest of it. I'm also planning to condense the experience milestones into a smaller list, add some overland travel rules, and a magic system of some sort. This will eventually become the core system of Necrocarcerus if I ever publish that setting, and it's creative commons so you can use or adapt it for your own ends as well.
