I really didn't enjoy this hack. Granted, it's not horrible, but the problem is that it felt generic. Although the hack was seven levels, the levels didn't really pop back in my mind after playing them. There just wasn't that much effort put into making the game fun. That's, unfortunately, all I can say. Try to do better next time!
It is what it says on the tin. Level design could be better, as there are certain parts with just blank space, and overworld design could be better. But I can't say anything as I don't know how to make a hack.
Update: yeah there was an update
all it did was fix level 3's major glitch by changing the whole level ( https://youtu.be/97zKJykJxOo?t=4m12s ) and added a bonus level if you start a new game in the update (im mean)
oh yeah and i changed the amount of saves there are
