Very impressive for a jam game, incredible visuals and audio. The stage construction and patterns are really solid as well.
So difficult I couldn't manage to beat the boss on either mode, but it was frustrating/addicting enough that I tried for well over 10 (20?) times. Feel like I'm missing something in the relationship between the mechanics even though I'm pretty sure I understood all of them, including the healing.
Like they've said before, the swords coming from below and the tiny bullets feel very unfair and unpredictable. I have no idea what to do with the boss pattern that uses these bullets. A slow button would've been nice.
