Just because it's a variation of Tetris...
With 5-block pieces instead of 4, it's treated as something unoriginal? That's stupid! I loved this game. I found the 5-block piece gameplay difficult compared to that of Tetris.
This is just tetris with different modes. Boring as and not fun at all.
Pentrix? more like Tetris..... this is Tetris. original as hell, meh I like Tetris
This isn't really a Tetris-*style* game, it pretty much IS Tetris, only very slightly varied. So, what's to keep me here instead of going to play actual Tetris instead? Certainly not the soundtrack...
... but perhaps the fact the pieces are made of five rather than four blocks? The game plays significantly differently from tetris, although there are, obviously, many similarities!
