Ok my bad, I checked the game page and I needed to press R to recruit. First feedback is that it would have been nice to have UI to open and manage the soldier. The gameplay itself is quite good, I like auto chess and I like the idea of recruiting your army, gearing and training your troops. The recruiting panel could have been a great place to inject lore through some kind of "soldier file" where you get some generic but meaningfull information like their age and what they liked to give these name some humanity. Personally I trained a John with full accuracy and a riffle and he did survive 10 waves, I had high hopes for him, but he died :'(
Regarding the game balance, even if I started to buy the best recruit possible (rolling indefinidely to get those 12 coins soldier), I quickly realize that the best way was just to buy inexperience soldier in mass and give them saer while keeping your best trained soldier in the back of the battlefield... what a grim prospect right... ;')
Great game, it lacks polish, but it is still great and I had fun playing it. My only regret is to not have any idea about the game context ^^'
