So I enjoyed the map and the ideas behind it, great work on that! unfortunately in the evil frog part, I got stuck in a pit at the top left and got soft-locked :( The Player movement felt really smooth and the whole thing felt like a dream, so I think you nailed that! In future projects, I'd recommend breaking the game into smaller chunks for the player, so maybe only one or two coin missions, or a checkpoint system for the frogs.
One last thing to note is that the square hit boxes felt a bit unnatural given the hand-drawn aesthetic, so maybe incorporate minor improvements on that too.
All in all, this is a great first project, and more importantly a great building block to make even better games/projects in the future, so keep up the good work and stick to it!
