That's a really cool jam entry, well done ! I like how the parry mechanic changes the pace of the game !
I have two things that were a bit frustrating in my opinion :
- it has already been mentioned by other commenters so I won't get too much into details, but some weapons are way too slow to be fun to use. Maybe some more feedback on the cooldown could help, but I think it would be good to reduce it by a lot, unless it's something that oneshots enemies.
- I got stuck for a long while at the start of level 2 with two sword enemies that took an insanely long time to kill, with their weapon that shoots all around I could do them only one damage at a time...
Other than that, it was pretty fun ! Awesome job !
