Pretty enjoyable time overall! Well polished, and the visuals and sound are all great, especially high praise for the second boss theme. The orbit system is super interesting, although I only barely learned how to make it work, and it feels like any change is too gradual to actually be able to react to all the shots. The best thing you can do is to set up a stable, round orbit around the boss and control exclusively with teleports instead, which feels like it goes a bit counter to what you intended (maybe?).
Being booted back to the first boss after every death is just mean, haha. Nothing functionally changes in the previous runs, so it just feels like a deliberate time sink.
