Things to improve

• To be the first level dont make it too imposible, Damage of enemies is too heavy and get killed super fast i tried moving on the same side and they autoaim me, I had to do "Left, Right, Left, Right in order to avoid.
• Reduce the speed of bullets of enemies at least 30% less
• Why reducing my HP when I just land on the level?, is unfair and that will make player get angry at the game .
• Make the player reload with "R" is the most common FPS stuff to do. 
• There are some colliders in the stairs part that are annoying
