I have to confess: I do not like it. Looks "ugly/a mess" to me as it is a mix of "scaled pixels", vibrant candy colors, title font with gradient/color bar effect, pixel art ... and so on.I assume some stuff is animated (eg the block area is surely rotating front back front back or so) but it looks a bit ... it contains too many different art styles.
So I hope you just want to fool us a bit by presenting some rough "previz/sketch out" ... you can do better - so do!
Look to candy crush - the king of this sort of style.
background is all about voxels
starblock du pon??? ditch the du pon
I know you are going to say "but my game is different because..."
I counted 8 different fonts - you should have no more than 3
My first screenshot for the comp. It's a blend of 80's Crossfire and Bomberman, with a touch of Robotron...
