Thank you for the detailed feedback!
You have a great point with the meteors, I take note!
My take on the theme was mostly on the game mechanic with the power ups complementing each others and the slime growth becoming faster and easier as you keep growing, thus the "chain effect" from the title. I should have add some visual hints to the theme, nothing visually underlines that aspect.
Thanks again for the feedback, and glad you enjoyed my game! :)
