Hey Remisse! Wow, these kind of feedback messages are pure gold for us, as we're starting the journey of game development!
Thanks for taking the time and point out all the aspects you thought could be improved. We've mentioned in other messages and actually added into the game's page, but we're working on a post jam version of the game right now. Definitely adding coyote jump, and fixing a couple of bugs and issues we've found thanks to the community's feedback.
This is jus the beginning! Thanks for playing ;)
