What a beautiful game. The narrative is excellent and the action platforming is just simple enough, but challenging enough to make the moments between vignettes enjoyable experiences. I love the sound design on this. The sfx were minimal, but very juicy and rewarding.
The amount of polish is fantastic for a jam game. My only real feedback isn't about the game, but about your submission. I think the art in the cutscenes is beautiful and such a core part of the experience, but I think you should have put the gameplay front and center as your thumbnail, so that way when users are scanning the submission list they see something familiar (an action platformer), but that has very unique style and charm. Even better if it's a gif! I think you'd attract a lot more jammers, and then your awesome narrative is even more of a welcome surprise and delight. One suggestion on gameplay ... a slightly more generoug hitbox on the attack. In one of the late stage games those slimes were really bugging me! They felt just a pixel or two outside of my range, but as a player it would have felt more fair if my hit connected there.
Awesome game. Excellent entry. Your team should be really proud of this.
