Awesome!
I'm never thought Shoot 'Em Up game can combine with Roguelite, i also make my Shoot 'Em Up game now and already upload my prototype on itch.io.
I have a question about how to design enemy spawn logic in Roguelite stytle, i think i can make many enemy spawn patten and random it, but just use normal random to spawn may will let game be unfair, have some tip to solve this problem?
