A GOOD GAME with PIPELINE madness!
I listened to the piano-music which resulted in a raised sound and humor-score. If you've seen pianoplayers do arrangements like that live, you'll understand why. Long live the rag-time! :) Music-button on/off is a must when looped, or I'd be mental now. Thx.
The idea/style has been used before, but that doesn't matter, cause games like these never grow old as long as you keep the players occupied and challenged.
Improvements that can be made (but not directly necessarily):
1. New background for each level, or at least change the colours.
2. Add more music. (Good midifiles like that don't take much space)
3. To avoid early quitters, make the early levels harder
4. Add timelimit or a clock to mesure the used time from level 1 to the end. This will trigger the brainspeed of lagheads. (My head lags sometimes or get out of focus.)
5. Add a code to write in to enter a specific level in case someone (LIKE ME) have to close browser, reboot or quit. To do completed levels again = waste of time. Time is honey.
6. Right-click mouse turns the pipeline the opposite way. This will speed up the game.
(7.) I hope it will "pay off" to complete it - that it has an ending (with a wet t-shirt pic of Hillary Clinton etc).
(P.S: If you're interested in pipelines, I think you should watch a flashmovie about the subject! A friend of mine animated the toon known as "Roy's Pipeline".-)
Very good work, Terry!
