It's great that you made the attempt to infuse both of them at once, but the problem stems from the core gameplay that feels like two separate games. I can only ignore the moving character for long until it reaches the top. Additionally, having a mouse cursor being restricted to switching two neighboring blocks on left and right doesn't give enough flexibility to move blocks. With the player having to micro manage between positioning the player to be at the very bottom and doing the chaining to gain score in the meanwhile, it's not the most intuitive core loop. At least it's good the game scope is very small to allow trials and errors to be played out.
If you want to look at examples that does infuse color match and platforming more smoothly, you may want to look at some examples like Mr. Driller and Super Puzzle Platformer Deluxe. They infuse the player movement and action as integral to clearing blocks without having the cursor floating around and doing the work separately.
