Peeking mechanic is done pretty good, I like how you still have some time after being detected to kill a guy. Melee can hit through walls. Enemies can sometimes see you through half walls. Last seen icon is pretty random. Everything lacks impact, and clarity for my taste. Like it doesn't feel satisfying to kill a guy undetected, killng a guy using a gun doesn't feel satisfying as well, and that red bar isn't a good indicator that you're crouching. Going gun blazing feels more like a bonus than a main mechanic, enemies hit you right away when you're in their line of sight and that's a no-no because you can't avoid getting damaged, and nobody likes to get hit in stealth games. Holding the melee attack is useless and I do understand why it's even in the game. Why the game isn't resetting by itself after player death? Yeah, so you need to work on that graphics, but I bet you know that already. All in all pretty okay game

Hey. I think that the game idea is awesome. You can add some abilities and melee weapons, and it would be really cool to play.
Sneaking and combat is very engaging. There is a game that is called Hotline Miami that is very successful. You can check it out and take the best things from it.
I made a video about me playing your game. I hope you will like it. Also, I am hosting a jam(with prizes) that is going to happen at the end of the following September.
The video is here https://youtu.be/QODukv1PIxo
The link to the jam is in the description under the video.

It looks kind of promising so far but I think you need to think of ways to make it a lot more engaging

Could use a more fleshed out style but i know its early. feels good kinda like hotline miami. V polished mechanics already.

I like the whole "able to peek" thing and the AI is really well made(if i could know, where did you learn to make the AI like that?). You should add a scene that at least has a button to transfer you to the main game scene. Here are some suggestions, add multiple gamemodes and unlockables. That would really spice the game up. The animation and UI is also really cool. Overall, it's a pretty fun game, and it could be better if it had some better sprites.

Promising game !! Good proof of concept, and well done with the IA.
Maybe you can start make other levels, or add a menu at least.
It could be interesting that the IA will search in a zone instead of a point.
