Any details on the gameplay?
The color blocks are spawned randomly at one of the 16 spots outside the dots field and fly by.
You have to dodge around these but there is one block at the top of the UI. You have to collect a block which matches the color to score. You can also collect extra score blocks and extra time blocks.
There is also a level bar and as you score it fills it. When you have level up the blocks are getting quicker and spawns at a higher rate so it becomes challenging at some point.
But there is also a level mode where you sometimes have to collect a certain amount of colors or sometimes collect the colors in a correct order.
Sorry for the compliated description. It's quite heavy for my as a german to describe it correctly
