Not enough interesting things to do...
I kinda liked the design of the skeletal robot bunny.
Some of the graphics could have been a lot better - specially the fire. Also the bunny itself could have used some shading.
I liked the explosions though.
You really need to work on your button hitboxes. Make filled rectangles in the 'hit' frame so it's easier to click.
A bit lacking in stuff to do but as I said I like the designof the character.
Just work on brushing up on your drawing style now.
