Love the old-school gameboy-type aesthetic! It's a neat concept to play as the pipes. This game desperately needs a "speed up" button for when you think you've lined the pipes up correctly, like in Tetris how you can speed up how fast the blocks are falling down. That would take the fun / addiction levels up quite a few notches, I expect. Good work!
Nitpicks:
- Took me a while to figure out what the controls are (it's up and down on the arrow keys)
- That little music loop will be stuck in my head forever now
