Quite funny cinematics/transition videos. Other than that it is basic platformer with rigid movement mechanic.
Movement is the most important part on the platformer, you should work more on that to get it feeling really satisfying. Then you can spend some time on level design.
Also, I find this spamming in "cool game, rate my game" on other games quite distasteful. Did you even played and genuinely rated those games?
Anyway, congratz on finishing your first game jam, hope you had fun and keep improving!
