As somebody else already said, the click sound is great. I liked the ability to "squeeze" the cursor to fit through tighter spaces.
The enemies were challenging to see sometimes as they spawned and floated over the platforms to get at me. I feel like you could also reduce the angle of attack so there's more opportunity for players to hit them before they're able to approach you. Since they fly in at a high angle, it's difficult to get a bead on them since the space is narrow to navigate.
Overall really like this submission and think it's an impressive solo entry!
