Thank you so much for the comments. I regret that it seems somewhat unrelated to the topic. Originally, I planned to use two characters as the main characters and introduce the concept of enemies, but due to the short development time and my lack of an art background, I ended up with this abstract style. However, I will continue developing the game prototype in the next few days, incorporating all my original ideas and replacing the endless mode. I hope you can offer some suggestions then. Also, this game does run very well on mobile devices, but currently there is no input mode support; I will add that later.
