This is an interesting concept. It's an RPG. About RPGs. An RPRPG, if you will. I don't know if that's been done, but it's new to me, and I really like the idea of having to manage real-life events around fantastical battles.
It's definitely rough in its current state.
There are some major sizing issues. The iframe and/or embedded page is kinda messed up; it's much wider than it needs to be and stretches the whole itch page. The game itself, though, is cut off, and big chunks of the UI aren't visible at all. Going fullscreen fixed that, but it wasn't a good first impression.
The UI is pretty rough visually, but it's a game in its early stages so that's not really a big deal. Similarly, it would be nice to have some music and sound effects, but again the
To be honest I didn't play this game much. There's a lot of complexity to it, which is a double-edged sword. It means there's potentially a lot of depth and staying power to the game, but it also means that new players can get overwhelmed quickly and never really give it a chance. It's possible to manage and control complexity to ease players in and get them onboard, usually by trickling in mechanics or other aspects one by one.
At least in its current state, the game doesn't do that. Everything is thrown at me from the starting line, and there's very little in the way of help. There's a tutorial, but it only covers half of what I need to know, and I've forgotten most of it by the time the game actually starts. I have no idea what gear score is, what any of the stats mean, what the types of character are, or how the real world affects the raids or vice versa. I did a raid and lost, but had no idea what I did wrong or what I could have done to do better.
I may be preaching to the choir here, maybe this is something you already have in mind.
The other thing that seemed to be missing was any sort of progression or risk/reward. I could recruit all the players I wanted and nothing bad seemed to happen after losing the battle. I think this is something planned, though, so I won't say too much about it. It'd be interesting to see what you come up with for an overall gameplay loop here.
All in all, it's very much a prototype but I like the concept and I think it has a solid direction.
