Not too bad
What I liked about this was how well everything was presented. That might also be a negative, because at times it seemed a bit too simplistic. What also weighed it down was how there was no sound. I suggest you at least try to put some sound effects or music in this. At least you could have a song be part of it and just have a mute button to get rid of the sound. Level 5 was really the only one I am having trouble with.
What I also think is cool is that it's interesting when you have to collect all of the gems to move on. Well, I guess those are actually diamonds. What's also neat is how you're able to go so quickly. Unfortunately, it didn't have enough good things about it to recommend. I haven't played the original so I can't compare it at all.
