Both valid points. I colored the coins for two reasons : they are pretty and the perk "coins stain bricks" means that if a red coin hits a blue brick, that brick becomes blue (which helps with other perks like "picky eater" and "color pierce"). I think there could be a short text that changes once you perform the action, so "click to start", "catch the ball", "catch the coins for score", and "clear all bricks", then it would be gone once you finish the first level.
The game is great and clearly a lot of thought has gone into polishing! Congrats
FWIW it also took me a couple of levels to even realize how I was getting coins. A yellow glow around the coins or some shiny effect + clinky sounds would go a long way. The -2 +2 etc. callout numbers could also last longer on the page and just grow in size as they fade out? They were also quite hard to spot
The -1 numbers are when your coin multiplier drops, that part isn't really explained or intuitive. i'm not even sure of how to call it. It's the number of coins that will spawn when you break a brick, and is displayed on your puck. I guess if i displayed " 2 x " on the puck and made coins look like coins, everything would be a bit easier to understand.
