Like others have said, I like the intro a lot. It's a good way to set up the situation and the controlsAnimation's nice! I like the look and feel of the boss and it's attacks. I wish there was a bit more variety with the player character's attacks though. Maybe like a melee weapon at close range or something. Also, I was able to clip myself and the boss outside of the arena somehow.  

Beautiful animation!

Nice work! really like the artstyle is like cuphead

Fun animations and cool attack patterns for the boss!!

Wow! Like how many attack patterns are there? Really good entry, that intro is sick!

Too much obvious good things to tell, the difficulty, juice & feel, cool attack patterns, the fact you don’t see the enemy health keeps you on high tension all the way (“when are you gonna fall?!”) …

A few things I noted to improve:

• the colliders seem to be placed differently on the boss and player, making it not as obvious to know if you will get hit or not
• please find a way for non QWERTY keyboard users to play fine (changing region is meh)

good job!
