Ok. This is a good game.
Got me playing this game until beating the Top1 in the HighScore assigning mnemonics to the cubes and keys. A few suggestions for improving it: U can redistribute the blocks UI to the letters position, like this:
Also, u could try to redo the cover as it’s not pixel-perfect. The egg is too static to me. While I understand the fact that the egg is fragile, I need a reason for the egg sliding, but I’m probably too nitpicking with these kinds of things.
Apart of it, I think your game is reaching the top. Congratulations!
