I wasn’t able to get past the first boss unfortunately. Dying and returning to the start of the platforming section was pretty rough, it’d be great if you could respawn the player at the start of the boss instead.
The controls are also a little rough around the edges. I think adding some forward momentum to the basic attack would go a long way to making the attacks feel less stiff. As others have mentioned, the jump feels a little off too, I think due to the lack of air-control.
I love the art and music in this game. The art style is very PS1 and the character portrait (I only saw the player character’s portrait) during the cutscene was super polished. The first boss music was really good too. The environment art is also stellar, you should be proud!
