This is a pretty good idea for a game, but I got to the 2nd level, after figuring out how to get pass the jumps, when you attempt to attack something you just die and what is that on the 2nd level.
It's like you didn't feel like even making something and so you threw on a platter of crap which moves back and forth and plus you can't even kill it.
Suggestions for a second version (if there will be one) :
Health bar
Longer stages
Obstacles(example: spikes)
Checkpoints
Different sets of attacks
But, overall this was a good enough for 2 stars.
