I have a few icks with this game.
It's hard to enjoy the Game when the boss can see me when I'm Inside a room hugging the opposite wall. Timing doesn't seem to matter at all. the "walk" mechanic feels like an aesthetic choice rather than a stealth mechanic.
The boss seems to not have a pattern. I feel like I had to wing it and get lucky.
I have a few suggestions because I dont like JUST complaining, its rude and unconstructive.
* Difficulty slider (enemies have more\less health\less perceptive)
* Aiming sensitivity slider.
* Cover/stealth mechanics.
* Objectives/Reminders/Hints
It's an awesome game and original. I hope you further improve this game because it hits the good spots.
sorry for complaining.
