The problem is that this enemy (albino) has a different attack. Not the attack that would suit me.
By default, the albino enemy fires a homing ball and has a melee attack. In this case, melee attack is good. The ranged attack doesn't fit my idea, so I would definitely change it to something else. We are, of course, talking specifically about the boss, not about a regular enemy. Also, let its size also be a little larger than the green biomechanoid. The problem is that this enemy is very wide. The biomechanoid is more balanced in size, because it should appear from a cubic lift-cell.
The Cyclops from another game had an attack where he spat out multiple rocks that could bounce back at the player and damage them. I think it's very difficult to implement, especially on the first engine.
A boss with homing projectiles would fit into another chapter of my mappack, but that's a topic for future discussion. For the first chapter of my mappack, I would leave an enemy with a more suitable attack and size.
As a result, I choose a biomechanoid enemy.
