It's a really fun game so far.
The movement and combat feel great, you can constantly chain grappling to different platforms to evade enemies or move really quick, combined with some really good combo opportunities and generally good level design.
The story is wacky but I love it, the MC is really funny and I love the contrast between his edginnes and seriousness compared to everyone else, especially cause of how over the top his combat style is. I would say play even harder into the style and make the MC's gameplay sprites a little less chibi and more with his looks in the dialogue screens.
As for sound, I think its pretty good, tho the music doesn't fit much with the action nor is very memorable.
Overall, I really like it! There are bugs and such, but I didn't mind them, they all were minor goofy things which got a laugh from me (also the dialogue is pretty funny too).
Good work, and keep it going!
