I don't think I'm going to beat it, which is perfectly fine, but I love it.
The game is super engaging with a great pacing and rythm. It looks great, I love the boss design. It could benefit from some sound effects but the music is super catchy and it's super fun to play. It controls well with the right speeds and good feels. I like that everything about it is brutal, only one life (there's no checkpoint between phases, right? I don't think I've ever reached the second one so I wouldn't know), I can't make good use of the shield while dashing is strong but the trail kills us (I love the dash trail killing you, it's hilarious). What I've played of it is hard but fair, not sure about the next parts as I only saw them when ded but could not try to deal with them.
That's a very cool entry, thanks for sharing.
