Very cute game. I agree with Valonad that the menus could have a better layout and it would be useful to receive more feedback after selling a weapon. The news were helpful but something more immediate could have been nice too.
I got a bit lucky with my purchases and I was able to make the weapons that the characters required despite money being very tight. I was surprised that the events depended on the kinds of weapons that you sold, that was pretty neat. I was able to get the good ending first try!
