i love the artstyle and concept, which is a very unique take on the theme, and the game is extremely well polished as well. but the lack of music or even some small sound effects and the difficult fishing minigame are small cons. and i know theres another link to a better version, but im gonna write this review then check it out so that its not biased.
oh and i literally didnt realise that the purple ones arent to be collected before i read one of the comments in this game. so u should probably mention that in your tutorial as well
