That's great feedback. Thank you. 🙂 I'd like to return to this project again in the future, so it's definitely something I'll consider and try out.
I quite like the way the tentacles can burrow while you're shooting them, so there's this tension where you try to kill them as quickly as possible. But I agree that the time to kill can feel a little high. Maybe there could just be a weaker version of the same enemy that appears in higher numbers?
