Cool game! The 2d mixed with 3d was really neat! I think the projectile logic is a bit faulty as it sometimes just stays in the air not moving. Also, the jump was not too useful, at least to me, so maybe incorporate some mechanic to utilize the jump? As for the camera, I would recommend looking into cinemachine as it has really good options for smoothing out camera clipping since right now your view gets blocked at the bottom. Regardless, it was a fun little minigame! Good work!
