Overall a 3/5 game in my opinion. I only gave 4 stars to the art bcs the pixel art of the game is really good. Congrats on the art team for that. Love the title screen especially. AI or not it looks cool. Overall atmosphere and art style gave me Miyazaki vibes, especially Princess Mononoke
Controls need some work. Attack animation triggers a few miliseconds delayed after you press left click. Some times you need to press a few times for the character to turn left or right and charged attack is glicthed, it doesn't work.
Boss desing is artistically good but combat is pretty straightforward. First and third bosses have 2nd phases, but the attack patterns are too simple. I think this is the hardest part to pull of for designing a boss fight. 2nd boss is just running left and right.
I think there's a good foundation for a good video game here with some polish and magic touches here and there. Good job for the team and good luck !
