Thanks for playing! I really wanted feedback of someone who plays shmups. Glad you enjoyed it.
I haven't encountered this issue yet, there isn't supposed to be anything coming from behind or anything, maybe it's the missiles the ship launches at you if i have to guess, they don't get destroyed even if you destroy the carriership. you have to quickly increase the mobility and dodge those, maybe that can help. But i will look more into it if there is a bug that's causing it. Thanks!
