Tried it;
Better Menu Options, Practice is a bit more colorful though I think I was also talking about levels like Junker where they used the same Platformer box though I won't argue.
Practice included a new power-up, a sword, spiffy though we can't use the vines.
• While I see you didn't take the colored vine change into account, I was able to see the Hub better and understand a little about how the game works with the vine a little, not exactly as I stated but fair enough.
•Have better control in physics, also helpful
Just polish it, maybe add some multiplayer if it takes off well and your good to go.
