This is why there's an 'Alpha's' section.
You can attack with 'z'. The problem with this is that afterwords, the character stops being able to be controlled at all.
Everything moves too slow, the music is annoying, and the graphics are not pleasing.
Also, what's with the jumping? It's not smooth, and you can terminate it immediately, but not dynamically.
Overall, this could have potential, but major reworking would need to be done.
