Really enjoyed this! Simple, but fun. I really like platformer games with unique gimmicks, and even lacking something as simple as jumping really makes things interesting!
I actually remember seeing a game just like this on the google play store a loong time ago, like 8-9 years ago. It was called Annelids, a team-deathmatch sorta game where you dig around the map as little worms and use ropes to maneuver around.
Definitely not bad for 1 month of dev, and for probably one of your first projects. I quite like it, it obviously has some rough ends, but there's nothin wrong with that.
