Very neat!! I have never been so excited to get move left and right upgrades haha. Also the overworld map is very cool! Overall awesome game~ My one suggestion would be to put a random.range pitch code on your audio manager on things like the jump sound effect. That way it doesn't sound like the exact same jump sound every time :D Once again, great job!
Hey thanks for playing! The left and right upgrades were a very handy and cost effective excuse to have a tutorial haha, but also could expand a bit on it later by doing things like giving the player gravity but no movement. As for jump sound effect - it's actually in there but I think we could probably expand the range a bit further out:
