So I've worked out a few ideas and I've determined that less is better in most of these cases. Because I want this to be a more relaxed TTRPG, where the players and GM can decide on things together. So basically the motto is: "less number crunching and more imagination". 

I've determined at least for the first pass of the game there will be three main stats, one of them isn't even really a stat. The stats are Fun Energy, Stamina, and Size. I'm going for a much more cartoonish feel.  So I've decided to avoid death and HP. 

Fun Energy or FE:  Basically the magical energy of every clown and the stat that determines the number of magical actions they can do between rests.

Stamina: This is the stat that determines the number of physical stunts a player can pull off before they need to rest.  Its max number also determines a Clown's movement speed.

Both of the previous stats are like a well of energy the player pulls from. They diminish and run out as the player performs more actions.

Size: This is less of a stat and more of a set trait the player has at the start of their game but can alternate during play. The three sizes are small, medium, and large. Certain tasks are intended for certain sizes, such as a small clown's hands being used to unlock a door, or a large clown jumping over a wall. It's like a recommendation a GM can decide on for a task. But players can still attempt to figure out alternative methods.  Also, sizes can make for really diverse character designs : D 

When a player runs out of FE and Stamina their clown passes out. They reawaken after a rest. But I'm also imagining a few methods of rejuvenating a tired clown without resting such as sugar, music, etc.

There will be dice rolling in the game but, at least for right now, I'm working with low numbers so I think the player may have a single die to roll instead of a dice pool. I would like to test with a d12 at first. It needs more use in my opinion. 

Let me know what you think of all of this so far.
