- Love the simple visual style.
- The control is simple and good
- The gameplay idea is simple and fun
What could have been better:
- I would really like some sound effects and perhaps also some music.
- Make some delay between "Change polarity". For now you can cheat trough the levels by constantly clicking on the space bare.
- I would like to see more game mechanics and some more interesting level designs.
Overall an interesting start for the game. Well done.
