Quite challening and fun!
I urge you to keep making games and doing jams. this reminds me of my first games
I love to see so many first time devs.
I would suggest maybe a screen that says "you dies", or even just an animation or sound effect. The major thing is the art/graphics, but I know its not as simple as "doing better" and I love that you included animations and textures, even if they are simple.
(PS: Play my game, I need more ratings (if u have time))
