Hello Wanhus!! It's glad to know you're still alive!
OK long phrase cut short and let me share some actual thoughts and opinions.
-The damage of enemies in the very first woods I think it could be decreased by one of two.
-The post-hit invincibility I think it could be exntended by 3-5 frames more.
-The load data function is bugged and unfinished? I can't load my save file saved at the very first church, thus lost all my progress for a good chunck of minutes. For this reason the game effectively prevents me from making further adventure progress and checking further locations.
Anyway keep healthy and stay safe! Best luck to you guys!!!
