Hey! Thanks for trying it out and providing your feedback.
I struggled with what to call some of the powerups (originally the pickup was called Magnet, but I changed it to Tractor Beam so it would stay thematic. To your point, though, it may just be more confusing. Would Magnet make more sense? Or Pickup instead?
I plan to go back and adjust the Weapon / Power so that it does change sprites, I just am not great at sprite work so I couldn't find a sprite I was satisfied with at the time.
I agree Shields could be called options, though they do also damage enemies on collision. I only recently learned of the term Options for those and thought it might be confusing to newcomers, but perhaps it's more confusing not calling them Options. I'll give this some thought.
I don't recall the scoring working the way you're describing, but will do some experimenting and follow up on this.
Thanks again for the insight and for playing the game!
