a tutorial would really help with the game, also maybe a combo when dropping blocks, it could really help (see second pic) also, try adding a timer to the levels and have it as a score based thing! i also learned that if you spam the 'x' key, it could mess up the blocks identifying each other, kinda strange game, its interesting though! i really like it!
Thanks for playing and testing, I never thought of spamming X key and after trying it myself, I can see the glitch. This might take time to solve...
Anyways, I want this game to be relaxing that's why most levels don't have timer. Endless mode however has timer.
As for score based, this game is actually score based but I want to let player understands rock paper scissors rule in first levels. In certain levels, score will be important to solve them.
When you say letters should match the color, do you want them to have changing color? or mixed colors?
I'm going to darken the background later :).
