shield weapon is goated. like someone below said already, at some point it glitched and i was able to walk whe the upgrades screen was open, which lead to not being able to buy anything. still won that round because shield is goated. was not able to buy any upgrades though for the next day as well and that one i lost :( the goated shield still held out for long though.
overall, the game was very satisfying. i found the main character a bit too fast and couldn't gett on the correct interaction spot sometimes. also, i thought at first the buy with the "next battle" was going to be gossiping about the next enemy, giving some hints on what to upgrade, i think that could be cool :3c the mechanic took a few tries to get used to, but still was quite intuitive and easy to understand, a great plus for that. generally a great game i'd say!
