This is so cute, I like the idea of using mushroom as a main character.

Actually that was the idea I was developing =D

The mushroom was able (by finding the respective magic items) to use some magical powers, and by taking these items the cap color change and also de drawing of the white balls.

I agree about the hop looking a little odd.

Im not sure if youre still making this game, or were ever actually making it at all, but an idea I had was you can have an ability where the mushroom shoots poison spores for an attack, kind of like marios fireball attack.

ok when i saw the mockup (with the bg), i thought the mushroom eye was the mouth...my sight mistake@@

Overall it is still cute =3

I agree with thereisnocure... The jump looks a little bit flat, and the walk animation in not incisive... Try to animate the cap a little bit on this two events...

The hop looks odd as his body is extending to meet the ground, rather than striking the ground and propelling itself  off of it.

Also please make this piece transparent.
