This Tetris clone for the PSP written by Dragula96 is a very impressive homebrew game. The Trophy option really makes the game fun to play because you work to reach certain goals such as getting a certain score or beating a certain level. There are also three difficulty levels easy. normal and hard as well as two play modes Classic and invisible blocks where once a block lands in place it goes invisible so you have to remember where the blocks were and how they are positioned which isn't easy.
I give this homebrew game a perfect 10/10 rating
