Luck
I found this to be a great game but it like a few other jumping up platform games relies a lot on luck to try encouraging the player to keep going higher. I found that during some game play rounds that I would never once run into a health pack maybe more than once. In some cases I tended to get real lucky and get many power ups. During those rounds I tended to go up a lot faster as well.
The animation of this game is simply gray scale art and platforms that remind me of the lifts from Super Mario World that I used to play a lot when I was a lot younger.
The game play seemed to be simple which was jump up as far as possible whilst avoiding the green acid balls that reduce health. Along the way you can get bonus point balls, a super boost and some other power ups to help you go farther up in the game. Once you get level three and higher you have to start factoring in slippery platforms that require a bit of practice to land on without moving.
That and the acid ball shooters begin to appear more often making safety less and less of a factor and hoping to find a health pack more of a concern. However it is possible to go up very high without taking a single hit but it requires patience and the ability to wait for all the green acid balls to stop coming out for a moment so you can move up.
The music used was nice and helps you to calm down and relax as you jump up higher and higher just enjoying the feeling of sailing through the air like a eagle on a blimp. Really soothing and soft music though, did enjoy.
The medals are another nice aspect as they give you something to try and aim for as you get higher and higher in this simple game of luck. Some of the medals are hard to get while some are real easy to get which is good.
Overall, great game but mostly luck factored things. Fun time.
