Very ambitious project to try and do in a month.
As a user of unreal engine I noticed a few things immediately, namely the motion blur and lumen scattering issues. My personal advice is to just absolutely disable lumen as it just looks gross in my opinion. Also the heavy motion blur could do with disabling too.
The shop system actually seemed pretty cool but I only got to use it once before the next boss killed me and my only option was to close to desktop.
The character models and music were great but could have done with some smoother animations for the attacks of both player and boss.
I feel like this was definitely a victim of scope creep but I respect the ambition, and with a few more months it could shape up to be quite a good game!
