Thanks for letting me know. I just fixed that, uploaded a new version, please tell me if the problem persists.
Yes, now it works. At first I was confused as to what was happening and which character was I controlling. But I think I understand it now. Basically you have to multiple as much as possible for the red dot to destroy. This is a really nice thought. I enjoyed it but at after some point it felt that the game was playing by itself. 😅
Probably some power-up might make the gameplay for engaging. Like a power-up to reduce the speed of red dot for sometime.
