It has certainly kept me engaged from the start to the finish. All round solid gameplay but nothing exceptional.
The good:
Simple gunplay that feels pretty good. The chromatic abberation might be a bit too much but it does help sell the impact of the gun. The swordplay also feels pretty good in general and the controls just melt into my hands in such an intuitive way. Well done!
To improve:
There is a distinct lack of challenge and I find myself being somewhat 'meh' most of the time. Don't get me wrong, the game actually is pretty good and I did end up finishing the boss too. (Found this purple key but couldn't use it in the end for some reason?) I think simply making enemies deal a bit more damage, health pick ups a bit more scarce, might help.
