Redneg All Stars (Free Version) | Easy 1CC | PC
Freeware boss rush shmup made by Outside. It's really stylish and creative. The final boss's various stages were really fun. I enjoyed the dodging and it felt fair/approachable.
I'm not crazy about the boss rush format for that long though, it was stressful. I like when there's a little downtime in stages where it's just popcorn; the rhythm of the stage is important to me.
I would like to play other games by this developer.
