Thanks for the feedback! ^^
Yeah, there are definitely some items that feel more powerful than others right now, and the swiftness boots are one of them. We didn't have enough time to properly balance everything, but we'll definitely try to in the future! :)
And yeah, we'll definitely work on getting the UI more cohesive with everything else in the future. The other graphical style clashes are a bit intentional because of what we were trying to go for (different areas, such as the protagonist's homeworld vs. the pool area), but I also understand that there's a bit of a difference between the background and the enemies themselves. Thanks for playing! ^^
