Really solid platformer, I honestly wasn't expecting this to feel great, but I was pleasantly surprised. The jumping and moving around felt really good, and the art style was really charming. Only thing I noticed was that the level transition was a bit jarring, the music just glitches out during it. Still, really cool platformer!
Also, I noticed you're using payday music, but I'm pretty sure they don't allow explicitly using those in video games, and if something is not clearly stated as allowed, then it's not allowed, legally. Just saying that because you might get in legal trouble, stay safe!
