So just saw this was a thing on steam

I posted in the megathread too but figured it might be better as its own thread and posted it here too. So i was looking through steam for something to play and this caught my eye as a free game. How good is it as a f2p? i did do a quick search and saw it had gacha stuff (doesn't surprise me) also can someone tell me a bit about this game and how it plays? Thanks for any responses. If its better to make a whole post let me know. I dont know really anything about this game other than it has gacha and is free to at least try
