Loved the detail of being able to push the UI text. Not sure if intentional, but was something that felt inherently funny.
For being an action game, I’d suggest improving the jump. It was a little bit floaty, which made it hard for avoiding bullets in later stages. Also adding the ability to do short jumps/high jumps depending on how much time you hold the jump button is a welcomed addition for games like this one.
Congrats on your first finished gamedev project!
