Fun game.
I feel like the auto locking weapons should prioritise locking onto enemies of the correct colour however. I think the way its working is once it locks on to an enemy its says locked onto them till the enemy is killed? Since they do more damage to a specific colour I think even the switching from a half killed enemy would still be more efficient since it does more damage?
Lore drops are a nice way to add a collectable. Also for a non story focus game its a nice way to make the story something in the background that can be read when the player feels like it, not getting in the way of gameplay
