This game is REALLY cool, however, the boss is difficult in all the wrong ways.
The player feels clunky, one attack feels like it takes several seconds while the boss can perform an attack in 5 frames, additionally, it is annoying that the only unlockable attack is the one the boss can spam infinitely if the player is far away, or spam just an obscene number at any time, especially while the player is waiting for the attack to finally hit.
This might just be a me thing, but the dash should also be a different key, as "f" is right next to "d" on the keyboard, so to dash, one has to let go of one of their 4 vital movement keys and really needs to focus if they want to dash right.
I apologize if this seems somewhat negative, I fought the boss an obscene amount of times before I finally beat it so I still feel a bit of rage.
The positive notes:
- The boss looks REALLY cool
- The arena looks REALLY cool
- If the player wasn't so clunky, the boss's move set would be really fun to fight (I would recommend a faster attack that does less damage, that way the player has to get in danger more often to get a hit in, then can dodge the unlockable attacks)
- It captures the rage of Dark Souls quite well
- I am REALLY glad there is a lock on option
Overall, an AWESOME boss fight, it has a few issues, but it's still really engaging and quite a challenge. Good job!
