Hi, thanks a lot for your feedback, you made great observations that can help me, you're right, game lacks feedback , the objective was to eliminate all red characters before they kill yellow character, blue characters are following same movememt of yellow character and the red ones are always tracking yellow, I really appreciate if you try the game with that in mind.
I took some notes and I'll try to polish things up and take a look to the guides you provided. Thanks again for your help, I'm willing to try your games also and share my feedback.😊
