Thank you for your honest review! The game unfortunately ended up becoming a much more simple and unpolished experience due to the lack of time and me still learning the game engine.
A lot of mechanics had to be scrapped, namely the pickaxe, which currently has no other purpose other than progressing from the starting area. I should've spent way more time figuring out how to make the combat work, or at least removed the pickaxe to not cause confusion, I apologize for that.
As for the light mechanic, it's heavily inspired by the game Darkwood, where enemies are visible only in the light. That being said, I should have given the enemies more sound cues, but I was afraid they would then be too easy to avoid. While they are relatively easy to outrun, it does become a problem if you run into more of them and end up cornering yourself.
Giving the pickaxe actual use and adding combat will be the first thing I do when I start working on the game again. Thanks again for the feedback!
