Hey there and thank you! I wanted to keep the game simple and minimalistic and I didn't want to have big red cone of sights there. In a such short time I didn't figure a better way how to do it so I kept it clean.
It could be something as simple as adding a small animation or a liittle sign above the monsters head when it's about to spot you. Like, if you're far away nd approaching him, since it's not clear how far he can see, maybe add some feedback that if you get closer or don't find cover soon, he'll see you. Or maybe have the screen turn red or dark as you enter his field of view. Maybe it doesn't work with the kind of game you want it to be, but i think it's worth giving it a try o see how it affects the experience. Just saying. Again, I really liked your game and I want to see what it becomes if you keep working on it.
Oh sure. I'm already planning on how to make it better. Removing the gun and adding only a dagger so you have to sneak up behind enemies, adding crouch and making the grass not so tall so it's not confusing when they see you behind the grass, and also adding a 1-2 sec period with visual feedback (flashing light or eye above enemies) when enemies see you so you can still hide in that period.
