It's nice hear you guys are still so motivated to update the game ! a small tutorial would certainly be a great addition !
That plus a better overall progression : here it feels a bit like there's a lot going on directly from the beginning. Maybe you could start with the most simplistic version of the game, then after each round you add one new game mechanic at a time (weapon gear, new enemy, armor, new stat, etc...)
I'm curious to see how the game will evolve :)
