In fact, I didn't have a lot of planning at the time I developed the game. All my friends and people who played the game complained mostly about the part where multiple enemies appear at the same time. But I thought this would be good since I love games with a lot of clutter and visual pollution, but it doesn't seem to work very well in the game.
Thanks for the video and for having seen potential in my game, I will improve the game to fix these negative points.
