This was so much fun!!
I was a little confused on the tutorial at first because I thought the enemies were gonna look different from the husk I connected. But I restarted the game and realized I missed the part about "using them against their own kind." Once I got that, it all made sense!
I love how each enemy has a different attack you can use! Really adds to the fun of it! Also, music, graphics and level design are all fantastic.
The only thing I'd suggest is maybe a bit of a visual reduction or variety when the player is surrounded from all sides. I don't know if it was the lightning, the screenshake, or the fact that all the enemies were about the same color and exploding, but at that point it felt a little too chaotic. I didn't realize I could still get out and thought it was just a death animation... so maybe just a tad less there could really help orient the players, at least in the early levels :)
Also, as much as I love the idea of being chained to the husk forever, (very metaphorical!) logistically, it might be nice to have a feature where you can eject the husk to pick up a different one (perhaps it could be like a charged special attack, so it's not overused), since some of the enemies, particularly the 4-direction projectile ones, are a little hard to aim.
Really, really awesome work with this game! Best of luck in the jam!
