I am an absolute sucker for metrovanias! Your game is really impressive, great work!
Take a look at the game my friend and I came up with: https://itch.io/jam/gmtk-2019/rate/462146
It's called Vortex Evac. We also took a fairly established genre and re-imagined the fundamentals. We created a "single-stick" shooter where the player only has one bullet!
