Thanks for making a playthrough of the game! And yeah, combat is definitely hard to balance, especially for a horror game and a jam game. The original difficulty used to be harder, but I figured since most people will want to play something short and quick and would hate having to restart all over, I should reduce the difficulty to also account for varying skill levels.
The enemies used to hit a bit harder and had a bit more health, stamina regen timer was one second longer, and there were no health regen up to 40. I gotten so used to how combat in my own game worked that I thought it was still a bit too easy until I got a friend to do a playtest run and decided to make it easier lol.
But congrats on making it through! You managed to avoid one ambush on the right side path but missed a few hidden healthpacks!
