Wow thanks for the detail. A few things. 1. The green line is is to give you an incentive to move forward. as you push it forward it adds points to your momentum. 2. the enemies shooting through walls is a bug 3. the enemies scale with the game. Certain things scale with hidden timer like the enemies rate of spawn and health and other things scale with player momentum like speed and bullet speed. so when you get slowed down the enemies shots dont laser you but its also impossible to get fast enough to outrun the enemy bullets. but I agree the Enemy AI needs a lot work to make it function well with the main mechanic. As it is its a pretty stock follow and shoot AI from tutorials. Thanks for playing!
