I personally find the jump to be a bit weird, and I thought the level design was a bit rough in some spots. Though, I didn't complete all of it so maybe I sound dumb and lack credibility. For a first platformer, this isn't bad at all!
Thank you for playing!! Also yes, the jumps and level design is still janky, so I hope I get to improve it on a future release. All the feedbacks help so thank youu! (^▽^)
