Combining Tetris and a platformer? Yes, please! This game involves strategic placement of the Tetris blocks. Having the ability to UNDO the last move was a great feature. I progressed well until reaching the level that looks like S stacked onto of a 2. Moving the blocks along the serpentine path was doable but challenging. Ultimately too frustrating trying to set up so many steps to climb. But overall, for an unfinished game, this was very polished. I enjoyed it. :)
