Really solid! I liked the dark theme/atmosphere. As you mentioned, I needed to download a native build to get good performance.
The in-air momentum feels kinda janky - I felt like I could sometimes turn around and sometimes couldn’t. Would be nice if you could maintain some more air control overall (except maybe not after you dash).
The gun felt pretty nice, though it might be nice to give more feedback when shooting the eyes (before they get killed). Maybe the particles should be bigger?
Small bug I noticed, when fighting the Mother Eye, you could walk on top of the elevator and the music would restart.
Overall, great job! I enjoyed playing the game.
