In first try, i actually didn't know the pit is the cave i am supposed to get in, and i jump to the cliff on right side and get an eternal falling. After that i have a problem to tell which pit is for the lower level. So in my second try, i again stuck in an eternal fall in one of the pits.
the pixel art is kinda cute, i believe you can set the texture filter to turn off to match the pixel art style better.
the platform game system is functioning. not bad. but sometimes i can't perfectly feel the hitbox. it sometimes trigger a respawn when the character is still far from touching anything. And when the character switch direction, the sprite move quite far, which is quite unusual for this kind of game.
i can feel you develop this with heart. and i wish to see what game project you will create next.
