Not bad! This had some good atmosphere, and I sure wasn't expecting the thing in the mines to be that!
Only real "complaints" as it were:
It would be nice to have a way to turn off/down color correction, it made it really hard to tell what's going on sometimes
The one big late jumpscare was probably a little too much and unnecessary. Up until that point, game was excellent, that one just felt a bit too loud and unneeded.
Keep up the great work, I had a lot of fun with this though. You have a good foundation for making spooky games!
