Thanks for your interest! I haven't had the time to play and/or develop much -- there was almost 2 years between v0.4 and v0.5 because I only got to play it again then! That said, the rules are (I think) in a pretty good state since they're riffing off 24XX rules, which are already good. That most recent time I've been having fun playing both solo and co-op with a friend, using *ahem* actual pokemon in addition to randomly generated etymon... The game's free/pwyw so take it for a spin!
I do have a few ideas brewing on how to develop and refine the rules further, and of course it's still missing the all-important random tables... The tables just takes some time to sit down to write (I find more joy as a rules tinkerer than as a writer!), and I do want to playtest more before adjusting the rules again -- but real life is very busy, so I can't tell you when v1.0 or even v0.6 will drop. Sorry about that!
If it helps, I also have a mini GM companion to help with solo/co-op play, it could be backup for my lack of random tables.
