A brain sucking thrill
In my opinion, the most important thing in a game is the fun-aticism factor. Sure, it might be repetitive; sure, there are only five types of enemies or so; but it's so fun, you can't stop! You will find yourself frantically pressing on the arrow keys, jumping and shooting and jumping and shooting at several dozen enemies jumping on you from all directions.
Another neat option is the many weapons in the game, from the basic laser gun through the amazing flame thrower till the Star Wars Light Saber. You'll find yourself playing just to find the next weapon, if not for the ending.
Some of the puzzles are nearly impossible! I found myself reloading the same level more than a dozen times in order to get the right combination of keys required. Luckily, those puzzles are rare, only two or three in the entire game.
The Bottom Line
Wonderfully made. This side scroller will be an excellent way to spend your time.
