Stifle

Retro style game, remake of a homebrew project from the late 90s, initially coded using Turbo Basic on a 486 DX2/66! Defeat the evil Professor Barker from destroying the planet and make sure he can never return!
Please note that this is a very short game, only 7 levels and you should be able to complete this within 5-10 minutes. But can you get the maximum score?
