Hello Neeko!
For the aim lock, we took inspiration from games like Metroid Prime. Personally, would you prefer this mechanic? Would you like to remove it, make it activatable/deactivatable, or assign it to a key so that it only works on the targeted enemy when we want it to?
You’re right about the doors requiring too high a kill count. We’re also going to make sure that the spawn curve increases the longer you stay in the same room, to make it more and more intense.
Thank you for playing and for your feedback!
