Boss3: I assume you are talking about the close range attack. I guess the reason is the participation frames is not noticeable. Gonna redraw the animation later.
Boss4: Actually boss 4 is easier than boss 5 becuz there was plenty of delay state for player to attack. I was hoping the player can get the basic of the new parry mechanic and thus better prepared for boss 5.
Boss5: I put hours in drawing the animation for this boss. I was getting better in the pixel art animation after drawing other4 bosses. I was thinking the triple axe attack can present a rhythm based sword fighting feel. Glad you like the opening when player perfectly parried a combo attack.
I am thinking about adding more bosses to the game (free update for those who already purchased the game ) and further polish the game. The goal is releasing the game on steam.
Thx for your review on the bosses :D
