3/5 and 7/10. Good effort. Has some bugs and room for improvement.
1) more music tracks.
2) more moves or power ups.
3) sound effects! What's it sound like when an enemy dies or gets hit with a sword?
4) collisions. Moving platforms don't move the character, resulting in some cheap deaths.
5) no infinite continues.
Very good. Better than I can do, and I'm in my 30's. Keep up work like this, and keep pushing your envelope. Now make a 1.1 (bug fixes) or a sequel.
