Ok, so I got to the ripped fungus (awesome sprites by the way), beat him, got a ton of curses (after ripped fungus died, every small fungus I killed spawned an orb in the same place, so when I touched it I got like 10 curses at once), and on the next level (which was a level I had already played) I was completely unable to damage anything! I shot bullets like a machine gun but they didn't seem to do any damage because nothing died, I ended up dying then and there, my guess is that I got nerfed by the curses into doing 0 (or negative) damage.
Another quirk I found is that after beating a random level, the portal+curse didn't spawn, so I got stuck and had to reset.
Still, really fun game! I wasn't using the dash until I realized it could cancel the melee lag, and then it became my best friend!
My only real complaint is that I would've liked the curse texts to stick a bit longer, I rarely got to read the whole thing before it disappeared!
I also liked the sound, really cool music and sfx!
