Thanks for feedback!
1. I suppose i could add those.
2. Yes , it doesnt work exactly like tetris. I kinda wanted to add my own twist to it. You have bombs and beams to deal with those static blocks in other modes. Classic mode wasn't there originally when i started to develop this, but i thought i would add it since thats what people would expect from tetris type game.
3. You can't do that in original tetris either. That would also make it difficult to fit blocks in some places.
4. Rectange formation is pretty much core idea of this game.
