Game could use an additional fun factor, such as; beating a stage within a certain time or getting a rating on how fast you beat the stage. Also, it needs more interaction for the player, like allowing them to aim the starting direction of a new ball or maybe resetting balls when they get soft locked (as Toxagen mentioned in their comment). A settings menu is also needed to control sound, and screen size options and there was no quit button. Besides having two balls soft lock I ran into one bug where the option to spawn an additional ball of each color did not work. I don't feel like the game met the theme at all and didn't really fit the focus either. The only reason I wouldn't report it for not meeting the focus is that beating the stages faster could be interpreted as a race against time. All things aside, it has potential to be a good chill game. Good Job!
If you would like to give my game a play, I'd really appreciate any feedback on it. It is a multiplayer game, so I do suggest trying to play with a friend, but its not necessary.
