This is not a game.
This is an exercise in placing faith in your ability to view the invisible. You have to jump up on invisible ledges, without any indication of what's there, and then attempt to attack enemies which still end up out of your reach. I don't see the point of other weapons and another character if you haven't even implemented basic elements. I also like how the other character doesn't lead to anything yet.
It's a great start, but until you finish this, don't expect good reviews.
