Thanks for the feedback. i had implemented a wall-banging (bullets passing trough walls) feature but removed it because the game became too easy. The red walls are not windows, but walls that bombs can destroy. I'm lazy and haven't yet made the bullet destroy itself on collision yet.
This is my first game with AI, and I make so that it gives an enemy a random number every second. 1-3 is move forward, 4-5 is turn -3 or +3 degrees every frame and 6-8 is nothing. I'll definetly fix the AI, sound effects, AI LOS range and the layout scale.
But thanks for playing thus far. I'll probably post a new version in a couple of days.
