Well done on getting your first submission! I really like the hand drawn aesthetic and text, feels unique and you should definitely lean into this for future jams!
Some suggestions on the mechanics: The movement controller should be refined further - should be able to move left even when up or down is pressed etc. and vice versa. Boundaries of the walkable area should be visually made evident. While i think that the movement animation is quite quirky, and unique, the character sprite should still maintain dimensions as it is moving up and down and also have some idle animation.
Overall great start to your game jam journey, all the best :)
