Good changes. I would recommend to make more Levels(maby with 2 enemys).
And at the start the enemy could make a turn, couse if you spam the K Button at the start. You Always win. And if you hit The Enemy once He will be pushed all the way too the Edge maby with 2 or 3 he could hit the Edge.And if the enemy hits you,you automatycly die . I would eddit that you don't die if you get hit but only if you collide with the Edge.: )
