Opening with a visual novel style in school setting is already peak but then casually dropping the Isakai anime "I Woke Up As A Youtube Loading Spinner", I'm dying over here. 😂
And then, it kinda took a dark turn... I'm not sure if I would like it better if it stayed wholesome but either way I'm curious to see where you'll take this. Its always nice when someone wants to develop a jam game further, I think you got a nice start here.
I liked the puzzle-platformer gameplay. However, the start of the level was pretty much "run all the way right and die a bunch of times". It would be much much better if the checkpoints are closer to where you expect the player to stack body parts.
Also the contrast between regular sized humans and the Chinori really helps sell the little guy theme. So good job on that.
