Really like it, is a really clear aesthetic you wanted to portrait and i really liked it, it could use a little more time, but the fundation is really solid.
Gameplay wise my only critic is the Right click to collect, i ended up perma holding it, maybe you could make it so you have to spend 1 bullet to turn it on, and the make it turn off automaticly after shooting or dashing, this way, it has some limitations and risks. Nevertheless, thats only my dumb opinion, congrats on the game!
