Okay! :'(
Anyway, I like Mosi! <3
It's more advanced than Bitsy.

PS Just my wishlist for Mosi:

1) comments
// My Comment

2) functions (one function for different sprites)
{My_Function_Minus_HP 1}

3) numbers to string and strings+strings operations
{ set-var MyString {num-to-str My_Integer} }
{str-mix "Room-" {num-to-str My_Integer} "!"} // Array of strings

4) "OnStep" in Room and/or in World Scripts :'D
(scripts in rooms after any Avatar's step)

5) Clamp and Abs Math
{clamp My_Number 0 10}
{abs My_Number}

PPS I'll try to make the game without HUD for the Bitsy contest
